Question

The atomic mass of an element is equal to the:

Answer 1

Answer: It is equal to the sum of number of neutrons and protons.

Explanation:

Atomic mass of an element is defined as the sum of number of neutrons and number of protons that are present in an atom. It is represented as 'A'.

A = Atomic mass = Number of neutrons + Number of protons

For an element X having 5 protons and 6 neutrons, the atomic mass will be:

Atomic mass = 5 + 6

Hence, this is equal to the sum of number of neutrons and protons.

Answer 2

The atomic mass is equal to the number of neutrons, plus the number of protons, in the nucleus of the atom
