Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale.Email...
What is the atomic number?Atoms:Atoms are the basic unit of matter. Each atom has a dense nucleus composed of neutrons and protons. It also has a less dense outer electron cloud. Neutral atoms contain the same number of protons and electrons, which are positively and negatively charged, ...

Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
