Metals for positively charged ions and nonmetals form negatively charged ions.
Metals and nonmetals form ionic bonds.
Metals tend to lose electrons, so they form positive ions called cations.
metals
Metals typically form ionic bonds with nonmetals. Metals tend to lose electrons to achieve a stable electron configuration, while nonmetals tend to gain electrons. This transfer of electrons results in the formation of ionic bonds.

When 2 non metals form a bond together, it is usually a covalent bond.
Most of the time the bond between a metal and a nonmetal is ionic. However, there are some exceptions, such as BeCl2, which is covalent. The difference in electronegativity determines what kind of bond will form. Metals and nonmetals with a difference in electronegativity of >1.6 are considered to have an ionic bond.
Typically the non metals form covalent bonds. Of course some non metals will also form anions when they react with metals. Some metals can also can form covalent bonds however as their electronegativity is low these bonds are often polar covalent
When sodium and chlorine bond, they form an ionic bond. This is because sodium donates an electron to chlorine, resulting in the formation of sodium ions (Na+) and chloride ions (Cl-), which are attracted to each other due to their opposite charges.
Transition metals tend to have colorful ions and compounds.
Noble gases typically do not form bonds with metals. They have full valence shells, making them very stable and unreactive. Metals tend to form bonds with nonmetals to achieve a stable electron configuration through ionic or covalent bonding.
Two or more nonmetals would form a covalent bond.
