Question

How to find valency electrons

Answer 1

Answer:

The valency is the number of the electrons that an atom gains , loses or even shares during a chemical reaction , The valency is the number of electrons that an atom needs to gain or lose on order to achieve noble gas electronic configuration .

In the chemical reaction , the atoms try to reach the stable state by losing their outermost electrons ( as in case of the metals ) or by sharing a number of electrons with other atom (in case of nonmetals ) .

You should know the valency of the elements or the ions to write the chemical formula of a compound , Chlorine has a valency of 1 as it needs to gain 1 electron to achieve noble gas electronic configuration.

The atoms try to reach the stable state by gaining a number of electrons to complete the outer shell by ( 8 ) electrons ( as in case of nonmetals ).

Answer 2

Answer:

you can get the valency electrons in an atoms electronic arrangements by consulting
