Question

Define Atomicity?
Define Isotope? ​

Answer 1

Answer:

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.

Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.hope it's okay

Answer 2

Answer:

Atomicity - the number of atoms in the molecules of an element.

Explanation:

Isotopes - are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
