Question

define the following a] atomicity b] valancy​

Answer 1

a) atomicity - the number of atoms in the molecules of an element.

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

Answer 2

Answer:

a] Atomicity is defined as the total number of atoms present in a molecule.For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2.In older contexts, the term atomicity is sometimes used in the same sense as valency.

b] Valency: The combining power or the combining capacity of an atom is called its valency. Valency of an atom is simply equal to the number of electrons gained, lost or shared by an atom to achieve the nearest noble gas configuration.
