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.
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.
Atomic mass - Atomic number
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.
Essentially the 3 basic parts to an atom are a Proton, Neutron and an Electron. Protons have a unit of mass and a positive charge Neutrons have a unit of mass and a neutral charge Electrons have no unit of mass and a negative charge. When a neutron breaks off from another atom it becomes a free radical that is then absorbed by the receiving atom because it would have a spare neutron space because the number of neutrons must be identical to the number of protons otherwise the atom will radioactivity decay. Essentially the mass number changes because the neutron has a mass.
