The number of protons in the nucleus is what defines the element. If there are 3 protons, it must be lithium. If there are 6 protons, it has to be carbon. Etc.
For a neutral atom, the relationship between the number of protons and the number of neutrons is the same.
The atomic number of an element determines its identity. Each element has a unique atomic number, which is the number of protons in the nucleus of its atoms. This number defines the element and distinguishes it from other elements on the periodic table.
Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.
Isotopes of an element have the same number of protons in their nuclei (same atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference in neutron content gives each isotope unique physical properties such as stability, radioactivity, and atomic mass.
protons
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons

Elelments are determined by the amount of protons they have. While different elements can have the same number of neutrons and protons, no two different elements can have the same amount of protons.
