Question

Please help me its very urgent write down the electronic configuration of hydrogen

Answer 1

Electronic configuration of Hydrogen:-
"K" shell= 1 electron.
It has only one electron in its outer shell,so it have to take 1 electrons from others to make itself stable.
Thus,
Its valency is +1.

Answer 2

Hey there !!

Hydrogen :-
Atomic number = 1
No : of protons = Atomic number = 1

No : of electrons = No : of protons = 1

Electronic configuration = 1

There is only 1 electron totally in a hydrogen atom.
Hence , first shell of hydrogen would have only 1 electron.
Also , the number of valence electrons here is 1
Hence , its valency also is 1
