Question

with reference to periodic table explain the following 1. groups 2.periods 3.ionization energy 4.metallic nature​

Answer 1

Groups:

• The vertical columns arranged with atoms from 1 to 8 columns are called groups

Periods:

• The horizontal rows arranged with atoms from 1A group to 8A group are called periods.

Ionisation energy:

• ionisation energy is the energy required to an electron from the outermost she'll of a neutral gases atom.

• Ionisation decreases from top to bottom in a group and increases from left to right in a period.

Mettalic nature:

• Mettalic nature can be defined as how readily an electron can lose an electron.
• Mettalic nature increases from top to bottom in a group and decreases from left to right in a group.
