Whick of the following pairs of ions would produce an Ionic compound? 1. Positive Cations
2.Negative Cations
3.Negative Anions
4.Positive polyatomic anions
5.Negative polyatomic cations

A. 3 and 5
B. 2 and 4
C. 2 and 3
D. 1 and 3

D) 1 and 3

Explanation:

Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.
