Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
Elements with a lower proton number than fluorine on the periodic table include elements such as helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and neon. These elements have fewer protons in their nucleus than fluorine, which has 9 protons. The proton number, also known as the atomic number, determines the identity of an element on the periodic table.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
The particle responsible for determining the identity of an element is the proton. The number of protons in an atom's nucleus, known as the atomic number, uniquely identifies the element. For example, hydrogen has one proton, while carbon has six. This atomic number distinguishes one element from another in the periodic table.
The sum of protons in the nucleus of an atom is called the atomic number. It determines the element's identity.
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.

Proton number
The atomic number of an element determines the number of protons in its nucleus, which in turn determines its chemical identity. Elements with different atomic numbers have different properties due to their unique number of protons.
equal
it means no of proton in its nucleus which is the identity of an atom.
You need to clarify this question. Do you mean, "How is the number of protons determined in the periodic table of the elements?"
The number of protons in the nucleus of an atom determines the identity of the element.
Iodine has 53 protons.
Periodic table
Henry Mosely
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
Elements are listed by the number of protons they contain starting with Hydrogen which has one proton.
