Protons = Atomic Number
Electrons = Atomic Number
Neutrons = Atomic Mass - Atomic Number
*A note on Atomic Mass*
Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one.
*A note on Protons and Electrons*
The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
The number of neutrons in an atom can be determined by subtracting the atomic number (number of protons) from the Atomic Mass (protons + neutrons). The atomic mass is usually listed on the Periodic Table for each element.
Mass no-the no of proton=no of neutron
The number of protons in the atomic nucleus determines the atomic number of an element. Each element has a unique number of protons, which is equal to its atomic number.
The neutron number of an atom typically refers to the number of neutrons in the nucleus. It is not common for the neutron number to be a decimal value, as neutrons are whole particles. It is possible that the value provided is indicating an average or approximate neutron number for a specific isotope.
Neutron number is not conserved in radioactive decay processes. During beta decay, a neutron may convert into a proton, an electron (beta particle), and an antineutrino. This results in a change in neutron number.

mass number= no. of protons + no. of neutron
a neutron determines the atomic mass
Find the weight on the periodic table then subtract the proton numbers.
One way is to consult a copy of "The Periodic Table of the Elements". Great Q'n!
Mass no-the no of proton=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

The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
Neutron number is not conserved in radioactive decay processes. During beta decay, a neutron may convert into a proton, an electron (beta particle), and an antineutrino. This results in a change in neutron number.
The atomic number of uranium is 92, so its atoms have 92 protons in their nuclei. If uranium-235 absorbs a neutron, it would then have the mass number of 236. The number of neutrons is the mass number minus the atomic number, so the number of neutrons in the uranium-236 nuclei would be 236-92=144.
There is no element with the neutron number 30.69. Neutron number is always a whole number as it refers to the total number of neutrons in an atom's nucleus. The closest whole number to 30.69 is 31, so an element with a neutron number of 31 could be gallium (atomic number 31).
