Question

What is the difference between atoms, molecule,element and compound?

Answer 1

Answer:

atom : is a smallest unit in element which cannot be divided

molecule : a group of atoms

element:a group of atoms or molecules

compound:2or more elements

Answer 2

A molecule is made up of atoms that are joined together. So, while an atom is its own unique object, we get a molecule where those atoms come together.

These can be the same things, such as two oxygen atoms that are put together (O2), or they can be different atoms that are joined together like water (H2O).
