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.

Is barium hydroxide a cation or an anion?
Barium hydroxide is not a cation or an anion. It is a compound. It is made of barium ions and hydroxide ions.
Is barium a cation or anion?
Barium loses two electrons in a reaction, so it becomes positive or a cation.
What is the charge for CaCl2 cation or anion?
Calcium chloride is a salt; calcium is the cation and chloride the anion.
What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
Is silver a cation or an anion?
Silver is normally not a cation or an anion, it is an element. Once it becomes an ion however, it will become a CATION with a +1 charge (Ag^+).
Is barium hydroxide a cation or an anion?
Barium hydroxide is not a cation or an anion. It is a compound. It is made of barium ions and hydroxide ions.
Is barium a cation or anion?
Barium loses two electrons in a reaction, so it becomes positive or a cation.
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.
Is po43- a polyatomic anion or cation?
Phosphate (PO43-) is a polyatomic anion. The way to tell this is to look at the charge - an anion has a negative charge and a cation has a positive charge.
What is the charge for CaCl2 cation or anion?
Calcium chloride is a salt; calcium is the cation and chloride the anion.
Charge of BaSO4?
BaSO4 is barium as well as a sulfate anion. The overall charge of BaSO4 includes a +2 charge for barium, and a -2 charge for the sulfate anion.
What is the charge on the cation in the ionic compound barium sulfide?
It's 1+ Yeah
What is the diffrenece between an anion and a cation?
An anion has gained electrons and therefore has a negative charge, while a cation has lost electrons and therefore has a positive charge.
As a cation moves towards an anion what happens to the energy?
Energy will decrease because they are attracted to eachother. A cation has a positive charge and an anion has a negative charge.
What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
What is the formula for compounds formed from Ba2 and S2-?
Barium Oxide is BaO.Ba+2 is Barium positive ion (anion).
What ions that carry a positive charge called?
An ion with a positive charge is called a cation, and has a superscript + sign to the right of it An ion with a negative charge is called an anion, and has a superscript - sign to the right of it
