Metals have large number of free electrons, which are responsible for conduction of heat, electric current, etc. Hence metals are good conductors. Non-metal don't have such free electrons in them. Hence they are bad conductors. There are many such properties which differentiate metals from non-metals. for example, metals have a typical metallic luster ( except few), etc.
No. It is a solid metallic alloy.
Metallic oxides are compounds that consist of a metal atom bonded to one or more oxygen atoms. These oxides are typically formed when a metal undergoes oxidation by reacting with oxygen. Metallic oxides can have various properties and uses, depending on the specific metal and oxygen ratios involved.
Metallic compounds typically do not have distinct molecules like covalent compounds do. Instead, they consist of metal atoms arranged in a lattice structure, where electrons are delocalized and shared among many atoms, forming a "sea of electrons." This structure provides metallic properties such as conductivity and malleability. Therefore, while metallic compounds are composed of atoms, they do not form individual molecules.
No. Beryllium is a metal. Metals consist of a mass of individual atoms held together by metallic bonding rather than colvalent bonding as molecules are.
The forces which hold a metal together are called metallic bonds. They consist of delocalised electrons which bind all the atoms together.
groups 1,2, all the transition metals (3-12), 13,14 That is if you are counting metalloids, if not then you would exclude 13 and 14
All chemical elements (including magnesium) are formed from atoms.
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.

It is a mixture - partially metallic and partially non-metallic
Non-metallic
Sodium does not consist of molecules but of individual sodium atoms.
