Question

copper is a element but water is a compound why?​

Answer 1

Answer:

Copper is normally in the form of a solid, so it is easy to picture cutting a solid copper wire into smaller and smaller pieces. Copper is an element made up of copper atoms. If it were made up of more than one kind of atom, it would be a compound.

Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen. Hence, a molecule is the smallest subunit of a compound while an atom is the smallest subunit of an element.

copper contains only one element

ie Cu but water contains 2 elements
