Detailed explanation-1: -This ion has 22 protons and 18 electrons. So, to sum this up, an atom of titanium must have 22 electrons surrounding its nucleus. An ion of titanium can have a different number of electrons because it carries a net charge, i.e. is not neutral.
Detailed explanation-2: -If there are 22 protons, then there are 26 neutrons. The charge is 2+ which means there are two more electrons than protons, so there are 24 electrons.
Detailed explanation-3: -In the periodic table, the atom with 22 protons is titanium (Ti ).
Detailed explanation-4: -The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom. This is known as the atomic number, Z. The removal or addition of electrons to a neutral atom creates ions that have a net negative or positive charge.
