No. Atoms and molecules are what make up all chemicals.
Molecules
Yes, a molecule is a combination of two or more atoms covalently bonded.
Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11
All of them. Molecules are made of atoms, not pieces of atoms.
Molecules are composed of atoms bonded together. They are the smallest unit of a chemical compound that retains the chemical properties of that compound.

These are two forms of a chemical reaction. The first type is called synthesis and the other decomposition.
a molecuole is a chemical combination of two atoms
In a chemical reaction, atoms are rearranged, such that some atoms get out of some molecules and join other molecules.
Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
Chemical bonds are what form molecules from constituent atoms. When atoms share electrons the type of inter-molecular attraction is called a covalent bond.
The same number of each type of atom (each element) still exists after a chemical reaction. They simply attach to other atoms (or detach) in various ways to form molecules (or molecules break apart into atoms).
