Answer to Question #156012 in General Chemistry for Brie

Question

Bonds by sharing electrons that both atoms claim. Covalent? Both? Ionic?

Answer 1

An ionic bond is a chemical bond between two atoms in which one atom seems to donate its electron to another atom. Covalent bonds, on the other hand, appear to involve two atoms sharing electrons reach a more stable electron configuration. Some compounds contain both ​ionic and covalent bonds. These compounds contain polyatomic ions. Many of these compounds contain a metal, a nonmetal, and also hydrogen. However, other examples contain a metal joined via an ionic bond to covalently bonded nonmetals.

Here are examples of compounds that exhibit both types of chemical bonding:

NaNO₃ , (NH₄)S , CaCO₃ , KNO₂ , K₂SO4
