The charge of the ion is 2+.
This would be represented as Fe2+.
This charge is 2 +.
Cr3+
Fe3+
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.
Sc is actually atomic number 21, there are 21 protons, 21 electrons, and usually 24 neutrons
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.
Iron (II) Fe2+ Mass - 55.845 ~ 56 Electrons - 24 Protons - 26 Neutrons - (56-26)=30 By Ritwick Chaudhry
Chromium's atomic number is 24. A neutral atom of chromium would thus have 24 protons and 24 electrons. Since we're dealing with Cr3+, though, we need to subtract 3 electrons from this number, giving us 21.

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.
21 protons, 21 electrons and 24 neutrons in 21Sc45 isotope.

A positive ion.

24, considering that an electron has a negative charge and the number of protons (positivley charged) is 24, an atom has to be neutrally charged

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+.
