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.
hydrogen +1 in most of the compounds -1 in metal hydrides
Covalent bonds are more likely to be found in compounds containing only nonmetals. Metals typically form ionic bonds with nonmetals due to the large difference in electronegativity, while nonmetals tend to share electrons in covalent bonds to achieve stability.
It's ionic if it is bonded with hydrogen or other metals, and it's covalent if with other nonmetals, but since bromine is a halogen, it is most likely to form ionic compounds.
Even though there are about five times more elements that are metals than nonmetals, there are more nonmetals than metals found in compounds. Nonmetals form many more compounds than metals because living organisms are composed almost entirely of nonmetals. There are more than 8.7 billion living organisms on Earth.
Molecular compounds are typically made up of nonmetals. Metals tend to form ionic compounds with nonmetals, whereas nonmetals tend to share electrons with other nonmetals, resulting in the formation of molecular compounds through covalent bonding.
Compounds with covalent bonds form molecules not ions Compounds consisting of non-metals bonded to nonmetals do not form ions

Metals form compounds very easily with non-metals.
because metalloids usually have properties that are similar to metals and nonmetals
Metals and nonmetals form ionic compounds.

Nonmetals burning in oxygen form covalent type compounds, as compared to metals which form ionic compounds.
No, nonmetals can also combine with metals to form compounds. This type of bonding usually involves the transfer of electrons from the metal to the nonmetal, resulting in an ionic compound. Examples include sodium chloride (table salt) and calcium carbonate (chalk).
