Barium chloride; BaCl2
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 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.
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
Barium gives its two electrons to two chlorine atoms (to form chloride ions) and they form an ionic compound barium chloride.
The name for this ion is:barium ion
I believe that would be Barium nitrate or Ba(NO3)2
Barium ion = Ba2+ Hydroxide ion = OH-
A barium ion is denoted as Ba^2+.
barium ion is a cation. rest listed are anions.
The barium ion has a charge of +2. It loses two electrons to become positively charged.
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+.
A cation is a positively charged ion, while a chloride ion is a negatively charged ion made up of chlorine atoms. Nitrate ion consists of a nitrogen atom and three oxygen atoms with a net charge of -1. Chromite ion is a compound typically found in minerals and consists of a chromium atom combined with oxygen atoms.
