What are Ions?
charged atoms
1 of 19
When do positive ions form?
when atoms lose electrons
2 of 19
When do negative ions form?
when atoms gain electrons
3 of 19
Why are ions stable?
they have full outer shells
4 of 19
What type of ions do metals form?
positive
5 of 19
What type of ions do non-metals form?
negative
6 of 19
Group 1 elements form what type of ion?
1+
7 of 19
Group 2 elelments form what type of ion?
2+
8 of 19
Group 6 elements form what type of ion?
2-
9 of 19
Group 7 elements form what type of ion?
1-
10 of 19
Ionic bonding is between what type of elements?
metal and non-metal
11 of 19
What type of attraction is between metal and non-metal ions in ionic compounds?
electrostatic attraction
12 of 19
What kind of structure do ionic compounds have?
giant lattice
13 of 19
What does giant lattice structure mean?
'giant' arrangement of ions is repeated // 'lattice' arrangement is regular (not random)
14 of 19
What kind of melting and boiling points do ionic compounds have?
high
15 of 19
Why do ionic compounds have high melting and boiling points?
large amount of energy is needed to break the electrostatic attraction between ions
16 of 19
Why can ionic compounds dissolve easily in water?
water is slightly charged - water molecules form electrostatic attraction with ions in the compound and pull them apart
17 of 19
Why can't solid ionic compounds conduct electricity?
ions are not free to move
18 of 19
Why can ionic compounds conduct electricty in a molten state?
ions are free to move
