Question

define electronic configuration

Answer 1

$\textsf{\underline{\huge{Answer}}}$

In chemistry, electronic configuration is the distribution of electrons of an atom or a molecule in atomic or molecular orbitals. For example : - electronic configuration of Hydrogen is 1s1.

Or in other words, electronic configuration is the arrangement of electrons in the orbitals of an atom. As we know, atom comprises of subatomic particles such as electron, proton and neutron. This are considered for electronic configuration.

Answer 2

Answer:

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.
