For "only metals" the answer is alloys or intermetallic compounds, formed of course from atom of metals - the bonds are of metallic type.
All other chemical compounds contain atoms of chemical elements, metals or nonmetals.
An ionic bond forms between a metal and a nonmetal. Ionic bonding transfers electrons.
Nigger
ionic = metal + nonmetal covalent = nonmetal + nonmetal So your compound is covalent because P (Phosphorus) is a nonmetal and O (oxygen) is a nonmetal.
Two or more nonmetal or metal atoms form a molecular compound. Due to this bond creating chemical reactions, a molecular compound is also a type of covalent bond.
Various things. If it is a nonmetal and nonmetal it going to be a covalent bond. If it is a metal and nonmetal it is going to be an ionic bond. If it is a metal and metal then it is a metallic bond.
An ionic bond forms between a metal and a nonmetal. Ionic bonding transfers electrons.
electrons are transferred from the metal atoms to the non-metal atoms forming ions resulting in an ionic compound
There are ionic compounds which is a compound formed by a positive metal ion and a negative nonmetal ion. And there are convalent compounds which is a compound formed in which atoms share electrons.

No. It is a compound of a metal and a nonmetal. Magnesium on its own is a metal.
Salt is a compound of Sodium (Na) and of Chlorine (Cl), thus, it is a nonmetal because it is a compound of 2 nonmetals. Na is not a nonmetal it is a highly active metal. This can be easily googled.

SO3 is a compound and therefore is neither a metal nor a nonmetal, because these are types of chemical elements, not of compounds. This particular compound consists of two nonmetal elements, sulfur and oxygen.
Neptunium beryllide (NpBe3) is a solid chemical compound (not metal, nonmetal or metalloid).
