Detailed explanation-1: -The number of protons in an atom determines its elemental identity. NO TWO ELEMENTS HAVE THE SAME NUMBER OF PROTONS IN THEIR ATOMS. The number of protons in an atom is called the ATOMIC NUMBER of the element. Each element therefore has a unique atomic number.
Detailed explanation-2: -Every element will have a unique atomic number. Thus, we can say that protons will determine the identity of an element. The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present.
Detailed explanation-3: -The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
