What does barium plus 2 and chlorine -1 form?

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.


What type of ion would barium form if group 1 loses one electron to form ions with a 1 plus charge?

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+.

How many bromide ions can combine with one ion of barium to form an ionic compound?

Two bromide ions can combine with one barium cation to form an ionic compound, because a barium cation has an electrical charge of +2, while a bromide anion has an electrical charge of -1.

How many iodine ions are needed to balance out a barium ion?

A barium ion has a charge of 2+ and an iodide ion has a charge of 1-, therefore, two iodide ions are needed to balance the barium ion. Ba2+ + 2I- --> BaI2


What is the valency of barium chloride ion?

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.


What is the charges of the barium ion?

The barium ion has a charge of +2. It loses two electrons to become positively charged.
