Question

what is the electronic configuration

Answer 1

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below. 

Answer 2

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.
