An atom is made of smaller particles called protons, neutrons, and electrons. Protons and nuetrons are in the nucleus.
The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. The number of neutrons determines the isotope of an element. For example, the carbon-12 isotope has 6 protons and 6 neutrons, while the carbon-14 isotope has 6 protons and 8 neutrons. If the numbe of protons were to change, it would no longer be carbon.
Neutrons
This is the number of protons.
There is no exact number of particles in the world as particles are constantly moving and changing. However, estimates suggest that there are around 10^80 particles in the observable universe.
Neutrons are the subatomic particles that contribute to the mass number of an atom without affecting its chemical identity. They can be added or removed from the nucleus during nuclear reactions, altering the atom's isotopic mass without changing its elemental properties.
Ions and isotopes are both atoms of a given element with a different number of particles. While the number of protons in an element never change, the number of neutrons and electrons can. In an ion their is a different number of electrons, changing the charge, but having a negligible effect on the mass. Among isotopes the number of neutrons varies, changing the atomic mass but not the charge.
Neutrons
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
Protons are the subatomic particles that give an atom its identity. The number of protons in the nucleus determines the element's atomic number, which in turn defines the specific type of atom.
This is the number of protons.
The fact that 0 is the additive identity.

Neutrons are the subatomic particles that contribute to the mass number of an atom without affecting its chemical identity. They can be added or removed from the nucleus during nuclear reactions, altering the atom's isotopic mass without changing its elemental properties.
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
Because the protons keep their integrity/identity whilst the electrons act as 'glue' binding all the subatomic particles together.
Ions and isotopes are both atoms of a given element with a different number of particles. While the number of protons in an element never change, the number of neutrons and electrons can. In an ion their is a different number of electrons, changing the charge, but having a negligible effect on the mass. Among isotopes the number of neutrons varies, changing the atomic mass but not the charge.
The number of positively charged particles in atoms of a given element is equal to the number of protons in the nucleus of the atom. This number is referred to as the atomic number of the element and it determines the element's identity on the periodic table.
