Detailed explanation-1: -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-2: -The atomic number (represented by the letter Z) of an element is the number of protons in the nucleus of each atom of that element.
Detailed explanation-3: -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-4: -Element 44 contains 44 protons as 44 electrons.
Detailed explanation-5: -In case you forgot your high school chemistry, here’s a quick refresher: An element’s atomic number is the number of protons it contains in its nucleus. The heaviest element in nature is uranium, which has 92 protons.
