Answer:
3. option
Explanation:
- non metals present in last four to five groups in the periodic table.
- generally the first two groups are metals in a periodic table.
- after two group there is a mixture of metals and metalloids in the periodic table.
therefore general electronic configuration of the first 12 groups are:
ns^1-2,(n - 1)d^1-10
