Question

what is the valancy?how can it be calculated? ​

Answer 1

Answer:

the combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with.The valency of the atom of an element is determined by the number of electrons in its outermost shell, i.e. valence shell. For atoms with less than 4 or less electrons in the valence shells (i.e. valence electrons), valency = no. of electrons

Explanation:

Answer 2
