you can find something like that by just looking at the number on top of each element on the Periodic Table:]
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.
The charge of the ion is 2+.This would be represented as Fe2+.
CO32- ions consist of one C and three O atoms with two extra electrons, counting for the ion charge (2-).C: 6 p+ and 6 e-3*( O: 8 p+ and 8 e) = 24 p+ and 24 e-Ion charge: 2 e-Total in carbonate ions (CO32-) : 30 protons (p+) and 32 electrons (e-)
There can not be an atom with more electrons than protons, however to find the atomic mass of any atom disregard the electrons and add the number of protons and nuetrons together. The previous answer is correct in that the atomic mass is equal to the number of protons plus the number of neutrons. The atomic number is the number of protons and in a neutral atom the number of protons and electrons are equal. Atoms have can have a charge, they are then called ions. The way the become charged is either through the loss (oxidation) or gain (reduction) of electrons. Therefore it is possible to have a charged atom with more or less electrons than protons.
The given number of protons and electrons indicates that the ion is iron (Fe). Since the ion is neutral, the number of protons determines the element, making it iron. The number of neutrons does not affect the identity of the element since it can vary while still belonging to the same element.

Ion 2+=====
20 protons indicate that the particle has an atomic number of 20 and is thus, calcium Ca. Since it has two more protons than it has electrons it must have a charge of 2+. So, the symbol will be Ca2+.
The charge of the ion is 2+.This would be represented as Fe2+.
+2: 26 - 24.
Ferrous ions are iron atoms minus two electrons. An iron atom has 26 each of protons and electrons, as shown by the fact that the atomic number of iron is 26. Therefore, a ferrous ion has 26 protons and 24 electrons.
Calcium: protons are 20 neutrons are 20, 22, 23, 24, 26 or 28 electrons are 20
