Question

an element has 5 electrons in m shell. what is its valency?

Answer 1

the max capacity of l shell is 8 but here electrons are 5, therefore it will gain 3 electrons in order to attain configuration of nearest nobel gas i.e, argon. therefore valency is 3

Answer 2

Heya
Here is the answer
-------------------------------------------------------
-------------------------------------------------------
Valency is the combining power of an element, especially as measured by the number of electrons it has to share , loose or gain in order to form an octet. Since the given element has 5 electrons in its outermost shell ,then to complete octet , it has to gain 3 electrons .
Hence the valency of the element = 3
