It is not possible.
Mass no-the no of proton=no of neutron
mass number= no. of protons + no. of neutron
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
Adding a neutron to an atom's nucleus increases the atom's mass by the mass of the neutron itself. Neutrons are more massive than protons, so adding a neutron will increase the atom's total mass without changing its charge.
Atomic mass - Atomic number
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
A = Mass Number Z = Atomic Number N = Neutron A - Z = N
Bcoz mass no is no of proton + no of neutron
neutron plus protons = mass number cesium
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
The mass number of a neutron is 1, as it contains one unit of mass. The mass number of a proton is also 1, as it contains one unit of mass. In hydrogen, the nucleus usually consists of one proton, so the mass number of a proton in hydrogen is 1.
