Ions + Ionic bonding

Question 1

What are ions?

Answer 1

charged atoms

Question 2

How do they form?

Answer 2

when atoms either lose or gain electrons to get a full outer shell

Question 3

positive ion

Answer 3

cation

Question 4

negative ion

Answer 4

anion

Question 5

Elements in group 1 forming ions

Answer 5

Elements in group 1 lose 1 electron to form a 1+ ion

Question 6

Elements in group 2 forming ions

Answer 6

Elements in group 2 lose 2 electrons to form a 2+ ion

Question 7

Elements in group 3 forming ions

Answer 7

Elements in group 3 lose 3 electrons to form a 3+ ion

Question 8

Elements in group 4 forming ions

Answer 8

elements in group 4 do not form ions

Question 9

Elements in group 5 forming ions

Answer 9

Elements in group 5 gain 3 electrons to form a 3- ion

Question 10

Elements in group 6 forming ions

Answer 10

Elements in group 6 gain 2 electrons to form a 2- ion

Question 11

Elements in group 7 forming ions

Answer 11

Elements in group 7 gain 1 electron to form a 1- ion

Question 12

Elements in group 0

Answer 12

Elements in group 0 do not form ions as they already have a full outer shell of electrons so do not need to lose or gain electrons

Question 13

Do metals lose or gain electrons

Answer 13

metals always lose electrons

Question 14

What does ionic bonding occur between?

Answer 14

metals and non-metals

Question 15

What is an ionic bond?

Answer 15

The electrostatic attraction between positive and negative ions

Question 16

What structure do ionic compounds appear in?

Answer 16

giant ionic lattice
