Question

which pair of elements is most likely to form an ionic compound with each other?
a. magensium and chlorine
b. nitrogen and oxygen
c. barium and zinc
d. bromine and sulfur

Explanation:

Ionic compounds are formed between metals and non - metals. Magnesium is a metal (Group 2 element) and chlorine is a non - metal (Group 17 element). Nitrogen and oxygen are both non - metals (they form covalent compounds like \(NO\), \(NO_2\)). Barium and zinc are both metals (no ionic bond formation between two metals). Bromine and sulfur are both non - metals (they form covalent compounds).

Answer:

A. magensium and chlorine
