Question

1. why do you think the term ionic is used to describe compounds formed from a metal element and a nonmetal element?

Explanation:

When a metal and a non - metal react, the metal donates electrons to the non - metal. This electron transfer results in the formation of ions (cations from metals and anions from non - metals). These ions are held together by electrostatic forces in the compound. So, the term "ionic" is used as the compound is composed of ions.

Answer:

The compound formed from a metal and a non - metal consists of ions (due to electron transfer from metal to non - metal) held by electrostatic forces, so the term "ionic" is appropriate.
