Detailed explanation-1: -The number of protons is equal to the atomic number of the element.
Detailed explanation-2: -The Proton 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-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).
Detailed explanation-4: -The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
Detailed explanation-5: -The number of protons in an atom is called its atomic number (Z). This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
