4Be2+ or Be2+ cation.
The ionic symbol with 4 protons and 2 electrons is Be2+, which represents the beryllium ion. Beryllium normally has 4 protons and 4 electrons, but when it loses 2 electrons to become stable, it forms the Be2+ ion.
Ti2- would be the symbol for an ion with 22 protons and 24 electrons. This would be EXTREMELY unlikely to exist though. Ti2+ is more usual with 22 protons and 20 electrons. Ti4+ is even more stable with 22 protons and 18 electrons.
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
The chemical symbol for the ion with 33 protons and 36 electrons is As3-. This ion has a charge of -3, which means it has gained 3 electrons compared to its number of protons.
An ion with 20 protons has the same number of electrons in a neutral state. Since the ion has a charge of 2-, it has gained 2 electrons to become stable. Therefore, the ion would have 22 electrons in total.
The nuclear symbol would be ^44Ti, representing the element titanium, since the atomic number (number of protons) is 22 (20 electrons + 2 protons) and the mass number (protons + neutrons) is 44 (22 protons + 24 neutrons).
Number protons equal to atomic number. So the element is Helium

+2: 26 - 24.
The chemical symbol for the ion with 33 protons and 36 electrons is As3-. This ion has a charge of -3, which means it has gained 3 electrons compared to its number of protons.
find the difference between the number of electrons and protons, and then find whether protons(+) or electrons(-) are more abundant. if the difference was 2, for example, and there were (2) more protons than electrons, the charge would be written as: chemical symbol 2+
The alpha particle is a helium nucleus. Its symbol is 24He2+, meaning 2 protons, 2 neutrons, and no electrons.
108Sn+2
Magnesium, with a +2 charge.
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
Co 2+
An ion with 20 protons has the same number of electrons in a neutral state. Since the ion has a charge of 2-, it has gained 2 electrons to become stable. Therefore, the ion would have 22 electrons in total.
