Question 1

Ionic bonds will form when…

Answer 1

a metal and non-metal combine

Question 2

Metals from groups _, _, and _ will form _____ with set charges.

Non-metals from groups _, _, and _ will form _____ with set charges.

Answer 2

Metals from groups 1, 2, and 3 will form cations.

Non-metals from 5, 6, and 7 will form anions.

Question 3

What are cations?

Answer 3

Cations are a type of ionic bond. They are atoms that have lost electron/s and are positively charged ions. E.g. sodium and chlorine leads to sodium losing an electron and is then positively charged.

Question 4

What are anions?

Answer 4

Anions are a type of ionic bond. They are atoms that have gained electron/s and are negatively charged ions. E.g. sodium and chlorine leads to chlorine gaining an electron.

Question 5

What is a covalent bond?

Answer 5

A bond formed between non-metal atoms. The atoms will be connect by a shared pair of valence electrons because non-metals want to gain atoms to reach a stable arrangement.

Question 6

What is a molecule?

Answer 6

A molecule is a neutral particle of two or more atoms bonded to each other.
