An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
Alpha Particles
Fe 2+ is Ferrous Fe 3+ is Ferric

Alpha radiation, which is the same as helium-4 nuclei.

The calcium cation is (Ca)2+.
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
plus one
Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.
Bromine(Br) has a charge of +35 on its nucleus
28
Since the anion has a 2- charge, it must have two more electrons than protons. The number of protons is 18 - 2, which is 16. Since the element has 16 protons, it is element 16, which is sulfur (S).
A certain element forms an ion with 10 electrons and a charge of +2. Identify the element
Calcium donates two electrons (charged -2) in reaction with a nonmetal. Substracting this from the zero (of the non-charged element) it leaves the +2 charge of the ion Ca2+Ca --> Ca2+ + 2e-
No element or ion as stated can exist, because if it contains 23 protons and only 18 electrons, its net charge must be 23 - 18 = 5 plus, not 3 plus.
two elements with ions with a 2 plus charge are Sulfurand Oxygen
