GENERAL KNOWLEDGE

Detailed explanation-1: -Elements are determined by the number of protons. They are NOT determined by number of electrons, neutrons or nucleons . Only isotopes can have same number of protons. Two different elements cannot have same protons.

Detailed explanation-2: -Protons determine an element’s identity because every element is made of one type of atom that has a specific number of protons in its nucleus. Protons are one of three different types of subatomic particles found within an atom, along with neutrons and electrons.

Detailed explanation-3: -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-4: -The number of protons in the nucleus determines which element an atom is, while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo.
