Question

Pls give the best answer for this:
If an atom loses an electron then why its valency is positive and not negative and if an atom accepts an electron why its valency is negative and not positive?

For E.g. Na(2,8,1) loses an electron to become 1+ instead of 1-

HERE IS YOUR ANSWER.....

valency is the combining capacity of element to complete its octet.
Valency is neither positive nor negative ,it is the charge on the element which is positive or negative.

We know that an atom is neutral due to the presence of equal number of electrons and protons.
Now ,if an atom loses electron ,then there will be reduction in the number of electrons which will probably increase the number of protons in the atom.Thus the valency becomes positive.


Also ,when an atom accepts an electron ,then there is an increase in the number of electrons.This leads to the formation of negative charge in an atom.
