Answer 1

Non-metal atoms

Question 2

What is a simple molecular structure?

Answer 2

A small group of atoms joined together by strong covalent bonds to give individual molecules

Question 3

What is a giant covalent or macromolecular structure?

Answer 3

Millions of atoms are covalently bonded together in a giant structure (lattice)
