It could possibly be used for both? This would give a deeper understanding into other like examples, where it is a fine line between the determination of an ionic compound or a covalent compound. Why do you feel a need to classify it under one or another? Chemistry is not about having a list of ionic compounds and another list of covalent compounds. That's all there is to it. If I absolutely had to pick one, I would say it is an ionic compound. What does this mean? It just shows that trying to classify something as "ionic" or "covalent" is futile.

You've been a great help!Compounds are defined as substances containing two or more different chemical elements. They have distinct chemical structures characterized by a fixed ratio of atoms held together by chemical bonds. Here, we discuss two classes of compounds based on the bond type that holds the atoms together: ionic and covalent. Covalent bonds are characterized by the sharing of electrons between two or more atoms. These bonds mostly occur between nonmetals or between two of the same or similar elements.
Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled. Examples of compounds that contain only covalent bonds are methane CH 4carbon monoxide COand iodine monobromide IBr.
Covalent bonding between hydrogen atoms : Since each hydrogen atom has one electron, they are able to fill their outermost shells by sharing a pair of electrons through a covalent bond.
Ionic bonding occurs when there is a large difference in electronegativity between two atoms. This large difference leads to the loss of an electron from the less electronegative atom and the gain of that electron by the more electronegative atom, resulting in two ions. These oppositely charged ions feel an attraction to each other, and this electrostatic attraction constitutes an ionic bond.
Understanding Bond Prices and Yields
Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor.
Metals have few valence electrons, whereas nonmetals have closer to eight valence electrons; to easily satisfy the octet rule, the nonmetal will accept an electron donated by the metal. More than one electron can be donated and received in an ionic bond. Attraction of the oppositely charged ions is the ionic bond between Na and F. Covalent and ionic compounds can be differentiated easily because of their different physical properties based on the nature of their bonding.
Here are some differences:. Single covalent bonds are sigma bonds, which occur when one pair of electrons is shared between atoms. There are four hierarchical levels that describe the position and energy of the electrons an atom has.
Phosphorus pentoxide
Here they are listed along with some of the possible values or letters they can have:. Principal energy levels are made out of sublevels, which are in turn made out of orbitals, in which electrons are found. Generally, orbital shapes are drawn to describe the region in space in which electrons are likely to be found. Atomic orbitals : The shapes of the first five atomic orbitals are shown in order: 1s, 2s, and the three 2p orbitals.
Covalent bonding occurs when two atomic orbitals come together in close proximity and their electron densities overlap. The strongest type of covalent bonds are sigma bonds, which are formed by the direct overlap of orbitals from each of the two bonded atoms. Regardless of the atomic orbital type, sigma bonds can occur as long as the orbitals directly overlap between the nuclei of the atoms. Orbital overlaps and sigma bonds : These are all possible overlaps between different types of atomic orbitals that result in the formation of a sigma bond between two atoms.
Notice that the area of overlap always occurs between the nuclei of the two bonded atoms. Single covalent bonds occur when one pair of electrons is shared between atoms as part of a molecule or compound. A single covalent bond can be represented by a single line between the two atoms. For instance, the diatomic hydrogen molecule, H 2can be written as H—H to indicate the single covalent bond between the two hydrogen atoms.
Sigma bond in the hydrogen molecule : Higher intensity of the red color indicates a greater probability of the bonding electrons being localized between the nuclei. Double and triple bonds, comprised of sigma and pi bonds, increase the stability and restrict the geometry of a compound.Bond prices are worth watching from day to day as a useful indicator of the direction of interest rates and, more generally, future economic activity. Not incidentally, they're an important component of a well-managed and diversified investment portfolio.
Everybody knows that high-quality bonds are a relatively safe investment. But far fewer understand how bond prices and yields work. In fact, much of this information is irrelevant to the individual investor. It is used only in the secondary market, where bonds are sold for a discount to their face value. And when the bond matures, its face value will be returned to you. Its value at any time in between is of no interest to you unless you want to sell it.
And that's when it becomes important to understand the movements of bond prices. The chart below is taken from Bloomberg. Note that Treasury billswhich mature in a year or less, are quoted differently from bonds. T-bills are quoted at a discount from face valuewith the discount expressed as an annual rate based on a day year. For example, you will get a 0. Let's look at how we calculated this number.
A bond's price consists of a ". Handleor the whole number part of the price quote. In the 2-year Treasury, for example, that's It's colloquially called the "big number. The two-year Treasury's handle is 99, and the We must convert those values into a percentage to determine the dollar amount we will pay for the bond. To do so, we first divide 29 by This equals.
We then add that amount to 99 the handlewhich equals So, equals A bond's dollar price represents a percentage of the bond's principal balance, otherwise known as par value. A bond is simply a loan, after all, and the principal balance, or par value, is the loan amount.
The two-year Treasury is trading at a discountwhich means that it is trading at less than its par value. If it were "trading at par", its price would be If it were trading at a premiumits price would be greater than To understand discount versus premium pricing, remember that when you buy a bond, you buy them for the coupon payments. Different bonds make their coupon payments at different frequencies. Coupon payments are made in arrears.Covalent Bond. Phosphorus is a metal and oxygen is a metal.
Two metals create a covalent bond. I THINK it's a covalent bond because I researched it, but that's just a suggestion so you should probably look into that answer more.

Bond valuation includes calculating the present value of a bond's future interest paymentsalso known as its cash flow, and the bond's value upon maturity, also known as its face value or par value. Because a bond's par value and interest payments are fixed, an investor uses bond valuation to determine what rate of return is required for a bond investment to be worthwhile.
A bond is a debt instrument that provides a steady income stream to the investor in the form of coupon payments. At the maturity date, the full face value of the bond is repaid to the bondholder.
The characteristics of a regular bond include:. Since bonds are an essential part of the capital markets, investors and analysts seek to understand how the different features of a bond interact in order to determine its intrinsic value. Like a stock, the value of a bond determines whether it is a suitable investment for a portfolio and hence, is an integral step in bond investing.
The theoretical fair value of a bond is calculated by discounting the present value of its coupon payments by an appropriate discount rate.
It takes into account the price of a bond, par value, coupon rate, and time to maturity. The size of the U. Calculating the value of a coupon bond factors in the annual or semi-annual coupon payment and the par value of the bond. The present value of expected cash flows is added to the present value of the face value of the bond as seen in the following formula:. A zero-coupon bond makes no annual or semi-annual coupon payments for the duration of the bond.
Instead, it is sold at a deep discount to par when issued. To calculate the value of a zero-coupon bond, we only need to find the present value of the face value. Following our example above, if the bond paid no coupons to investors, its value will simply be:. Under both calculations, a coupon-paying bond is more valuable than a zero-coupon bond.
