1
Q
Why do Group 1 metals react in a similar way with oxygen?
A
The chemical properties of an element depend on how many electrons it has. As Group 1 elements all have 1 electron in their valence shell they all react similarly.
2

A
2, 8
3
Q
Define covalent bonding
A
Atoms bond by sharing electrons
4
