calcium atoms, sodium, chlorine, and sulphur atoms
There are many examples of atom, 106 in fact. Look at the Periodic Table of the elements.
Compound is made out of different types of atoms. Some of the examples are, H20, Co2, KMno4. Elements are made out of only the same atom.
Oxygen, nitrogen, and hydrogen are examples of chemical elements. They are the basic building blocks of matter and have distinct properties that define their behavior and interactions in chemical reactions. Additionally, they are essential for sustaining life on Earth.
because some atoms are bigger than others
H for hydrogen
Atoms of only some elements. The number of these atoms is extremely great, not millions.
An organic compound where one or more of its hydrogen atoms has been replaced by atoms of other elements is known as a functional group. This substitution can alter the compound's chemical properties and reactivity. Some common examples of functional groups include hydroxyl, amino, and carboxyl groups.

John Dalton, a british chemist, explained that elements are made of atoms and different elements have atoms of different mass
