Molecules are mostly made of non metals. Particularly in organic chemistry, we have carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur as the main components, and they are all non metals. Metals are also part of organic chemistry and they are even part of molecules at times, for example, hemoglobin includes iron, but in most cases the metals appear in the form of ions, rather than molecules.
It consists primarily of carbon, but contains other elements. There are different types of coal, which have different compounds. See link.
No,, the consist of only two elements, or two types of atom. But depending can consist of more than two atoms depending on the valences of the elements involved. Examples (covalent): H2O, H2O2, CO2, SF6, Cl2O7, Examples (ionic): Na2O, Na2O2, CaF2, Fe2O3
yes
Two or more elements are chemically bonded.
Ionic bonds are between metals and nonmetals. Covalent bonds are between nonmetals andnonmetals.Also covalent bonds consist that they share the electrons to get a full outer level but on the other hand ionic bonding consists in giving and taking away!

Elements are atoms, atoms are elements. Elements are not larger objects made up of smaller things (atoms). Elements are specific species' atoms, which have a specific atomic mass which gives rise to the characteristics of the element. Compounds are composed of elements. It is important to note the difference between a compound and a molecule; the words, although often used interchangeably, have aspecific meaning in chemistry. A molecule is a certain type of compound in which the elements have bonded covalently. As such, all compounds are not molecules, but all molecules are compounds.

Atoms, molecules made of numerous types of atoms, compounds which are made of molecules and elements which are made of atoms.

HTML consists of many types of elements.
If yoy think to diatomic (atoms of same element) molecules: O, N, Cl, F, Br, I, H.
