how are the following related number of valence electron of the different element present in the same group
Answers
Number of valence electron is same for the elements belonging to same group of periodic table.
Consider the group-1 element and their electronic configuration
Elements electronic configuration
Litium 2, 1
Sodium 2,8,1
Potassium 2,8,8,1
Rubidium 2,8,8,18,1
cesium 2,8,8,18,18,1
Francium 2,8,8,18,18,32,1
Number of shells will be same for the elements belonging to same period of periodic table.
Consider the period-2 elements with their electronic configuration.
Elements Electronic configuration
Lithium 2,1
Berilyium 2,2
Boron 2,3
Carbon 2,4
Nitrogen 2,5
Oxygen 2,6
Fluorine 2,7
Neon 2,8. hope it help full please mark as brilliant
