1. Eight (8)

2. Eighteen (18)

3. Thirty-two (32)

4. Sixteen (16)

The period and group number of the element with Z =114 are:

Elements with an electronic configuration 1s²  2s²  2p⁶  3s²  3p⁶  3d¹⁰ 4s²  4p⁶  4d¹⁰  5s²  5p³ belong to the group :

The outermost electronic configuration of the most electronegative element is :

Sodium generally does not show an oxidation state of +2, because of:

1. High first ionization potential.

2. High second ionization potential.

3. Large ionic radius.

4. High electronegativity.

The pair that has both members from the same period of the Periodic Table is
