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.
It is chromium-51 and the symbol is ^51Cr
Electrons have a negative charge. Thus, a species with more electrons than protons will have a negative charge. The compound with 20 protons and a minus two charge must therefore have 22 electrons.
If an atom has an overall neutral charge this means that the number of electrons are equal to the number of protons in the atom. Take a transition element as an example say Titanium which has an atomic value of 22 meaning it has 22 protons and 22 electrons as protons are positive and electrons are negative the overall charge is neutral.
18 protons 18 electrons 22 neutrons
Titanium's Atomic Number is 22, that gives you the amount of protons (22) and electrons (22) in 1 nucleus. Then for the neutrons you take it's atomic mass and round it, and now it's 48. Then take 48 and subtract the amount of protons (22) and get 26... So to make sure you got this right the # of protons is 22, the # of electrons is 22, and the # of neutrons is 26.
Argon has 18 electrons and protons...Neutrons is 22
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+.
+1
22
12 + 10 = 22 charge
12 + 10 = 22 charge
In a neuteral atom no. of electrons=no. of protons no. of protons=22 and atomic number is given by no. of protons=22 Hence Atomic number is 22
Electrons have a negative charge. Thus, a species with more electrons than protons will have a negative charge. The compound with 20 protons and a minus two charge must therefore have 22 electrons.

18 protons 18 electrons 22 neutrons
Protons: 21 Neutrons: 29 Electrons: Normally 21
18 protons and electrons and 22 neutrons.
28 Protons = +28 charge 22 electrons = -22 charge +28 + -22 = +6
