What is the mass number, atomic number, total number of neutrons, total number of protons, the total number of electrons, make an electronic configuration of the following:
4
Mass number — total mass of nucleons is considered as the mass number of the atom.
- mass number = mass of protons + mass of neutrons
Atomic number — total number of electrons or total number of protons is known as its atomic number.
- Atomic number = total number of electrons or total number of protons
Neutron — it is chargeless sub-atomic particles.
- it is denoted by n and present in the nucleus.
- total number of neutrons [n] = Mass number[ A] – Atomic number [ Z ]
Protons — it is +ve charge of the atom.
- present in the nucleus
- total number of protons = atomic number of its element
Electron – it is a -ve charge of the atom.
- it is revolving around the nucleus in the orbit.
- total number of the electron = Atomic number of its element
Electronic configuration — The distribution of an electron in the shell or orbit is known as electronic configuration.
- it also helps to predict whether the element is a metal, non-metal, metalloid and noble gas.
- Electronic configuration of the helium atom is as follows
- 4 = 2
Thus, the mass number is 4, the atomic number is 2, the total number of neutrons is 2, the total number of a proton is 2, the total number of electrons is 2, and electronic configuration is 2.
