1
Q
What are the two ways atoms join together to form compounds?
A
1) Sharing electrons (covalent bonding)
2) Transferring electrons to achieve stable electronic structures (ionic bonding)

A
7 electrons
5
Q
Describe the combining of group 1 and group 7 elements (3)
A
- atoms of metals in group 1 combine with non-metals in group 7
- by transferring electrons
