Concept explainers
(a)
Interpretation:
The given compound is to be identified as either an ionic compound (i.e., one containing ionic bonds) or a covalent compound (i.e., one containing only covalent bonds).
Concept introduction:
If elements in a compound have large electronegativity differences, ionic bonding can occur. A more electronegative atom acquires electrons given up by a less electronegative atom forming oppositely charged ions. The electrostatic attraction between the positively charged cations and negatively charged anions forms the ionic bond. Most ionic compounds consist of a metal (the elements from left side of the periodic table) and a non metal (the elements from right side of the periodic table), whereas most covalent compounds consist of nonmetals only.
