Because by losing two electrons from the neutral atoms, a barium ion acquires a noble gas electron configuration.
Barium is in group two of the periodic table. Based on the information known for group one, it can be predicted (correctly) that barium will lose two electrons to form an ion with a plus 2 charge. Thus, the resulting ion in reactions of barium is Ba2+.

Each ion of barium can combine with two bromide ions to form an ionic compound due to the 2+ charge of the barium ion and the 1- charge of the bromide ion, resulting in a neutral compound.
One iodine ion is needed to balance out one barium ion, as both ions have a 1+ charge.
Barium hydroxide (Ba(OH)2) is formed when a barium ion (Ba2+) reacts with a hydroxide ion (OH-) in a chemical reaction.
Barium has a 2+ charge while chlorine has a 1- charge, so they combine in a 1:2 ratio to form the compound barium chloride (BaCl2). In this compound, the two chloride ions balance the 2+ charge of the barium ion.

Barium chloride; BaCl2
The most common charge of barium is +2, which means it typically loses two electrons to form a 2+ cation.
The charge on a barium ion is typically +2. This is because barium (Ba) commonly loses two electrons to achieve a stable electron configuration, resulting in a 2+ charge on the ion.
The name of the barium ion is simply "barium ion." It is a cation with a charge of +2, formed when barium (Ba) loses two valence electrons.
2+
One iodine ion is needed to balance out one barium ion, as both ions have a 1+ charge.
The valency of a barium ion is +2. Barium chloride (BaCl2) consists of a barium ion (Ba^2+) and two chloride ions (Cl^-), which gives the overall compound a neutral charge.
The barium ion has a charge of +2. It loses two electrons to become positively charged.
