All of the metals form monoatomic cations (have only one atom) examples are potassium, K+; Iron, Fe2+,Fe3+
Polyatomic metal cations are rare Hg22- is probably the most likely one to be encountered
Aluminum (Al) always forms a 3+ cation in its 3rd period of the periodic table.
Silver
This ion is the hydrogen cation.
Monatomic molecules
Cations are always positive, whatever they're of. Ooh, or is that anions? Yeah, on second thoughts I think cations are negative. Hang on a minute, I'll check......nope, I was right first time. Cations are positive.
No. Like other metals potassium forms a monatomic cation.
No. Like other metals potassium forms a monatomic cation.
Cesium is a cation, as it has a positive charge due to losing an electron.
The cation is the metal "Cu", otherwise known as the element Copper.
No, carbon is not monatomic. It is a chemical element that typically forms covalent bonds with other atoms, such as in carbon dioxide (CO2) and methane (CH4).
Oxygen is an element. It normally forms anions.
Aluminum (Al) always forms a 3+ cation in its 3rd period of the periodic table.

18 electrons.
Gallium is a metallic element. It forms cations Ga3+ and Ga+
