The atomic number
The number of protons in an atom's nucleus determines its chemical identity.
Elements are identified by number of protons on the periodic table. Number 15 is Phosphorus.
The number of protons in a nucleus is called the atomic number, usually identified as the symbol Z. It defines the element in the Periodic Table. In a neutral atom, ie not ionised, there is an equal number of electrons
The atomic number of an atom is determined by the number of protons it has.
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.

Elements are identified by number of protons on the periodic table. Number 15 is Phosphorus.
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.

The number of protons in an atom is its atomic number.
Their atomic number, which represent the number of protons in the nucleus. This will also be the number of electrons in the unionised state of the atom.
The atomic number of an atom is equivalent to the number of protons in its nucleus.

The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
