Neutrons add MASS to an atom.
Particles in an atom with no charge are called neutrons. Neutrons are one of the three subatomic particles found within an atom, along with protons and electrons. They are located in the nucleus of the atom.
When neutrons do not add to the charge of an atom, the number of protons remains the same, so the atomic number stays constant. However, the mass number of the atom increases because neutrons contribute to the mass of an atom without affecting its charge.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
The mass number of an atom is determined by the number of neutrons and protons. Since you already know the number of neutrons, you just need the number of protons, then you can add them together. I happen to know that iodine has 53 protons, so that means that the mass number is 127.It is the protons and neutrons added together so when you add 53 and 74 you get 127! Hope that helped a lot!! :):):):):):):)
no, they don't. instead they make up the nucleus of the atom. protons and neutrons are made of quarks, which are held together by gluons.which means that the nuceuls and electrons together make the atom.
Neutrons are subatomic particles found in the nucleus of an atom. They contribute to the overall mass of the atom but do not affect its chemical properties. The number of neutrons in an atom can vary, leading to different isotopes of the same element.
It is 3 because you have to add the neutrons and the protons.

To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.

Mass number/Atomic Mass
When neutrons do not add to the charge of an atom, the number of protons remains the same, so the atomic number stays constant. However, the mass number of the atom increases because neutrons contribute to the mass of an atom without affecting its charge.
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
no, you add the protons and neutrons
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
yes it is
