Questions and Answers

What type of elements typically form Ionic Compounds?

Alkali metals and alkaline earth metals

Noble gases and halogens

Transition metals and metalloids

Metals and nonmetals (correct)

What is the role of metals in the formation of Ionic Compounds?

They make up the anion, or negatively charged portion

They have the highest electronegativity

They make up the cation, or positively charged portion (correct)

They completely accept electrons from nonmetals

What happens to the electron configuration of a metal when it forms a cation in an ionic bond?

It loses electrons from its outermost energy level (correct)

It gains electrons in its valence shell

It remains unchanged

It becomes more electronegative
