Which of the following statements is true about an ionic compound?
A
It has a discrete molecular formula that represents an individual molecule in the solid state.
B
It consists of molecules held together primarily by covalent bonds between nonmetals.
C
It forms when two nonmetals share electrons to complete their valence shells.
D
It consists of cations and anions held together by electrostatic attraction.
Verified step by step guidance1
Understand the nature of ionic compounds: Ionic compounds are formed from the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).
Recognize that ionic compounds do not consist of discrete molecules; instead, they form a lattice structure where ions are arranged in a repeating pattern.
Recall that covalent bonds involve the sharing of electrons between nonmetals, which is characteristic of molecular compounds, not ionic compounds.
Note that ionic compounds typically form between metals and nonmetals, where electrons are transferred to complete valence shells, rather than shared.
Conclude that the true statement about ionic compounds is that they consist of cations and anions held together by electrostatic attraction.
