Question

Write the names and symbols of two most reactive metals belonging to the group 1 of periodic table explain by drawing electronic structure how is a one of the two metals react with the

Answer 1

From the periodic table group 1 metals in order of reactivity is given as follows :

1) Lithium

2) Sodium

3) Potassium

4) Rubidium

The most reactive is Lithium followed by Sodium.

Their electron configuration is given by:

Sodium has 11 protons hence its electron configuration is given by :

Sodium = 2 : 8 : 1

Lithium has 3 protons hence its electron configuration is given by :

Lithium = 2 : 1

Group 1 metals react by losing one electron from the outer most energy level.
