Anything in the second column of the Periodic Table: beryllium, Magnesium, calcium, etc. AND many of the transitional metals (though they can also be 3+, 4+, or even more), commonly: iron, nickel, zinc, manganese.
It is true that compounds formed from ions will form in such a way that the charges balance out and the compound has not net charge. An example might be aluminum with a plus 3 charge (Al^3+) combining with a chloride ion with a minus 1 charge (Cl^1-) to make aluminum chloride, where there will be 1 Al^3= and 3 Cl^1- to make AlCl3 (no net charge).
The most familiar one is aluminum, which can form ions with a charge of plus 3, for example in compounds such as aluminum oxide.
Ionic. lithium has a charge of plus one, bromine has a charge of negative one.
potassium positive bromine negative
The element with 10 electrons when it forms a cation with a 1 plus charge is Neon (Ne). Neon has an atomic number of 10, which means it has 10 protons and 10 electrons. The cation is formed when an electron is removed from Neon, leaving it with 9 protons and 1 electron, giving it a 1+ charge. Neon's atomic number: 10 Neon's electrons when forming a cation: 10 Neon's protons when forming a cation: 9 Neon's charge when forming a cation: 1+

Common salt and other such ionic compounds
Ionic compounds are compound consisting of a metal plus a nonmetal. The metal and the nonmetal both have charges that you can find on the Periodic Table, and they have to balance each other out. For example, you have MgO (Magnesium Oxide). The magnesium is the metal, the oxygen is the nonmetal, and they both have a charge of +2 and -2, so the subscripts cancel each other out.
+2 (plus 2)
These compounds are CuSO3 CuS CuCl2..
