Question

Which general electronic configuration of the element does not represent a nonmetal?Also explain.

1.ns²,np⁴
2.ns²,(n-1)d^1-10,np⁵
3.ns^1-2,(n-1)d^1-10
4.ns²,(n-1)d^1-10,np^1-6​

Answer 1

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
