Concept explainers
Interpretation:
Mass number of iron atom that has 31 neutrons has to be found out.
Concept introduction:
The total number of protons in an atom is said to be its
The total number of neutrons and protons of an atom is said to be its mass number. By using the total number of protons and neutrons all the atoms can be identified. Mass number is denoted by “A”.
Total number of neutrons present in an atom can be found out of finding the difference between mass number and atomic number.
