Positively charged ions
Barium hydroxide is not a cation or an anion. It is a compound. It is made of barium ions and hydroxide ions.
positive ions are called cations, while negatively charged ions are called anions
For example the cation Bh7+.
A cation (metal or ammonium) and an anion.
Potassium nitrate has 1 cation: K+ The other part (nitrate) is an anion: NO3-
Sodium is an elemental metal, found in the Periodic Table. When it ionises( looses) an electron it becomes the Sodium CATION (Na^(+)). Remember ions that have a positive charge are CATIONS, and ions that have a negative charge are ANIONS. Slo the chloride ion (Cl^-) is an ANION. Collectively they are ions.
The positively charged ion is the cation. Negatively charged ions are called anions.
Aluminum has trivalent cation. It is Al3+
A positive ion is called a cation.
The cation is always written first in a chemical name. Cations are positively charged ions, while anions are negatively charged ions. The convention is to write the cation first, followed by the anion.
Cu2+ is a cation as are all positive ions. One way to remember is to think of the "t" in cation as a plus sign.
Silver, Ag+ NO3- Cations are the positively charged ions in a compound so in this case Ag+ (silver) is the cation.
