They are held together by either a ionic bond.
We would need to know what unit you mean to be able to answer.
Metals are held together by metallic bonds. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together. Metals are made up of closely packed cations rather than neutral atoms. The valence electrons of metal atoms can be modeled as a sea of electrons. The valence electrons are mobile and can drift freely from one part of the metal to another. Metallic bonds consist of the attraction of the free-floating valence electrons for the positively charged metal ions. These bonds are the forces of attraction that hold metals together.
Metals have metallic bonds.
Covalent bonds hold non-metals together by sharing pairs of electrons, enabling them to achieve a stable electron configuration. This sharing of electrons results in the formation of molecules or simple molecular structures.
Hold polar molecules together
they have a strong hold of electrons!!!
H2SO4 is not metals. These two can go together and make H2.
If the metals are melted together the result is called an alloy, if not melted together the result is called a mixture.
Non metals are grouped together because of their similar properties. They are placed in groups-15,16 and 17

Some metals are not strong enough to be able to hold tons of weight
Covalent bonds hold atoms together. Ionic bonds hold ions together
