Answer 2

• 1, 2, 3 charge

Gain 1, 2, 3 charge

Question 3

are group 18 ions common?

Answer 3

no

Question 4

What is an ionic bond?

Answer 4

An ionic bond is a bond which involves a transfer of electrons so that both atoms have full valence electron shells

Question 5

How are ionic compounds named?
for example, an ionic bond between lithium (+1 anion) and fluorine (-1 cation)

Answer 5

Anion goes first, followed by the cation with the suffix, “ide”

eg. lithium fluoride

Question 6

Answer 6

ionic

Question 7

What is a covalent bond?

Answer 7

A covalent bodn is when two atoms share an electron in order to fill both shells

Question 8

(element type)

Answer 8

non metals

Question 9

What are metallic bonds?

Answer 9

Metallic bonds are bonds that form between metal atoms, where electrons are in a pool between the metal atoms
