Question

What is the atomic number of an element? How does it differ from the mass number?​

Answer 1

Answer:

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.

Answer 2

Explanation:

Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. The atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (AMU, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
