Answer to Problem 27E
Explanation of Solution
Given Info: The compound is
Explanation:
A covalent bond is formed when electron pairs are shared by two atoms. A stable covalent molecule is formed only when the octet rule is followed for the atoms which share electron pairs. A covalent bond is formed when two nonmetals combine or compounds that are gases, liquids or have low melting points.
Ionic bonds are formed by electrostatic interactions between an electropositive and electronegative atom. An ionic bond forms when a metal and a nonmetal combine or a metal combines with polyatomic anions.
