It is Lr, which is the chemical symbol for Lawrencium.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
Lawrencium has 103 electrons and protons. The number of neutrons is different for each of the 12 isotopes of Lr.
The neutral atom of lawrencium has 103 electrons.
The number of protons in an atom's nucleus is the Atomic number.
The number of protons in an atom's nucleus determines its chemical identity.
The number of protons in a nucleus depends on which element it is. ( The number of protons is the decider as to which element it is. ) The number of electrons in an atom is the same as the number of protons in the nucleus, but none of the electrons are in the nucleus. Rather, they orbit around the nucleus like planets round a star.
The atomic number reflects the charge number of the nucleus. It is always equal to the number of protons found in the nucleus.
The number of protons in the atomic nucleus is equal to atomic number.
