Define electronic configuration?? ​

Answer 1

Answer:

The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. The valence electrons, electrons in the outermost shell, are the determining factor for the unique chemistry of the element

Answer 2

Explanation:

As we know the formula for arranging the electrons in the electronic configuration.

=> 2n² .

And the names of the cells are K, L, M, N and so on .

So ,

In K = 2n² = 2(1)² = 2

In L = 2n² = 2(2)² = 8

In M = 2n² = 2(3)² = 18

In N = 2n² = 2(4)² = 32

In 0 = 2n² = 2(5)² = 50

So the electronic configuration of the element Having atomic number 100, is = 1 .

And the valency = 1

Valency = Number of Valence electrons in an element.
