Valency is defined as the combining capacity of an atom or a molecule. If the number of electrons in the outer shell is between one to four, the compound is said to have positive valency.

Is valency positive or negative?

Can Valency be negative? Loss of electron or electron gain called atom charge, Positive charge will be attained by donating an electron and negative charge vice versa. So valence has no sign, Charge has both positive and negative signs.

Is valency always positive?

Valency is the combining capacity of an element. The total number of electrons in the outermost shell varies from 1 to 8 there for the combining capacity will always be 1,2,3,4,5,6,7 or 8. Therefore valency is always positive.
