Mn has 25 protons.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.
In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
Cu2+ has 29 electrons (since copper has 29 protons) and 27 protons, after losing 2 electrons to become a positively charged ion.

B. Electrons are shared. Covalent bonds involve the sharing of electrons between atoms.
The ion carbon C4+ has 6 protons and 2 electrons.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
Lead will always have 82 protons. If it has a 2+ charge, that means there are 2 more protons than electrons, so there are 80 electrons.

Cu2+ has 29 electrons (since copper has 29 protons) and 27 protons, after losing 2 electrons to become a positively charged ion.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
