Question

What is the difference between atomicity and valency?

Answer 1

Valency is the combining capacity of an element which depends on the electrons present in the outermost shell. Valency differs from atom to atom but in a group the valency is same for all elements. ... Atomicity is the total number of atoms present in one molecule of an element or a substance.

Answer 2

hey mate here is your answer..........

Atomicity:-

Atomicity is the total number of atoms present in one molecule of an element or a substance.

Valency:-

The combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with.

For example, "carbon always has a valency of 4"
