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.
This ion is the hydrogen cation.

Monatomic molecules
Neon is a monatomic gas, meaning its atoms exist independently rather than in molecular form. In its solid state, neon forms a crystalline structure where individual neon atoms are arranged in a lattice. However, it does not form molecules like diatomic or polyatomic gases. Thus, neon is classified as a monatomic element in both its gaseous and solid forms.
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.
This ion is the hydrogen cation.

Aluminum
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
