Question

how to find the valency of given no of protons is 5 and given no of neutrons 6

Answer 1

Hey user !!

Here's the answer you are looking for

Total number of protons = total number of electrons.

So, number of electrons in the atom is = 5

In order to find valency, we need to find the number of electrons present in the outermost shell of the atom.

To find the number of electrons present in the outermost shell of the atom, we need the electronic configuration of the atom.

So, the electronic configuration of an atom with 5 electrons is 1s² 2s² 2p¹

Thus, the outer shell contains 3 electrons.

Therefore, the valency of the atom is 3.

Answer 2

given:-
no of protons=5=atomic no of element.
here, atomic no is 5.
so By the use of electron configuration ,
we get, 2,3.
also the valance electron=valency.
hence the valency=3 ANS

I hope this will help you.
