In its ionic state yes.
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.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.

Mahnesium is a bivalent element; the cation has the electrical charge 2+.
No, barium does not have a charge of negative two. Barium is a metal element with a charge of +2.
Calcium typically forms a +2 charge by losing its 2 valence electrons.
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
Oxygen typically carries a charge of -2 when forming compounds.
An element with 46 protons and 44 electrons would have a net positive charge. This is because protons are positively charged and electrons are negatively charged. The difference between the number of protons and electrons is 2, resulting in a net charge of +2. Thus, the element would be a cation with a charge of +2.
The charge on calcium in CaBr2 is +2. This is because calcium is a group 2 element and typically forms 2+ cations in compounds.
The charge of Li₂X depends on the identity of the element X. Lithium (Li) has a +1 charge, so in the compound Li₂X, two lithium ions contribute a total charge of +2. To balance this, the element X must have a charge of -2. Therefore, if X is an anion with a -2 charge, such as oxide (O²⁻) or sulfide (S²⁻), then the overall charge of the compound Li₂X is neutral.
The element within period 2 with the greatest nuclear charge is neon. This is because neon has more protons in its nucleus compared to the other elements in period 2, giving it the highest nuclear charge.
