How do elements form compounds?
By reacting together and gaining or losing electrons. Or by sharing electrons
1 of 12
How are ionic compounds held together?
By strong forces of attraction between the positive and negative ions. (ELECTROSTATIC ATTRACTION)
2 of 12
What type of atoms are involved in ionic bonding?
One non-metal and one metal
3 of 12
What structure do ionic compounds have?
Giant lattice
4 of 12
Whats the overall charge of an ionic compound?
zero
5 of 12
Whats covalent bonding?
Atoms sharing electrons
6 of 12
What type of atoms are involved in covalent bonding?
two non-metals
7 of 12
How are covalent compounds held together?
Strong covalent bond
8 of 12
What structure do most covalent compounds have?
Simple molecules
9 of 12
What structure do some covalent compounds have?
giant covalent lattice (also known as macromolecules)
10 of 12
How are atoms in a metal arranged?
Closely packed in regular layers
11 of 12
How are metals held together?
The positively charged ions are held together by the 'sea' of free electrons from the outer shells. The electrons act a bit like glue
