Interpretation:
The total number of neutrons present in the atom that has
Concept Introduction:
Atomic number for each and every element is a unique one. This is the total number of protons that is present in an atom. As the atom is electrically neutral, it can also be said that the total number of electrons is the atomic number. Atomic number is represented by the symbol Z.
Mass number is the sum of the number of protons and neutrons inside the nucleus of an atom. This gives the number of subatomic particle present inside the nucleus. Mass number is represented by the symbol A.
From atomic number and mass number, the number of each sub atomic particle can be found.
Complete chemical symbol notation can be given as.
An element is a pure substance that cannot be broken by ordinary
