No, positive 2. :)
2+
Barium is an alkaline-earth metal, which means it has two valence electrons. To fulfill the octet rule (see below), it wants to lose those two electrons. When it does this, the number of positive protons is greater than the negative electrons; the ion is positive. Positive ions are called anions.
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.
The compound formed by barium ions and chloride ions is known as barium chloride. The chemical formula for barium chloride is BaCl2, as barium has a 2+ charge and chloride has a 1- charge, requiring two chloride ions to balance the charge on one barium ion.
The barium ion has a charge of +2. It loses two electrons to become positively charged.
The negative ion for barium sulfate is sulfate (SO4) with a charge of 2-.
Ba has no charge overall but the Barium ion has a 2+ 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.
Barium forms a +2 charge, along with all other group 2 metals.
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.

The barium ion has a charge of +2. It loses two electrons to become positively charged.
Barium gives its two electrons to two chlorine atoms (to form chloride ions) and they form an ionic compound barium chloride.
A permanganate anion has a single negative charge, while a barium cation has two positive charges. Therefore, the formula for anhydrous barium permanganate is Ba(MnO4)2.
The chemical formula for a compound with one barium ion and two chloride ions is BaCl2. The barium ion has a 2+ charge, while the chloride ions each have a 1- charge, so it takes two chloride ions to balance the charge of one barium ion.
