The ion Mg(2+) has 12 protons, 10 electrons and 12, 13 0r 14 neutrons depending on the isotope.
19 Protons and 20 electrons
11 protons and 10 electrons
Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.
Mn has 25 protons.
Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.
The ion carbon C4+ has 6 protons and 2 electrons.
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.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
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.
