Atoms of different elements are different because the have different numbers of protons. The atomic number (the number of protons) is what defines which element the atom is. For example, all atoms containing 1 proton are hydrogen. 2 protons are helium, 3 lithium and so on. See the Periodic Table of elements for more. Atoms of the same element can still be slightly different in the number of neutrons they have; these are called isotopes. Their properties stay the same but they have different masses. You need not consider electrons too much because most atoms have a relatively loose hold on electrons and don't account for much mass BUT!!!! electron configuration is the main factor for determining how elements will react with each other.
What else can I help you with?
What do you know about two atoms if their atoms numbers are different?
the two atoms belong to two different elements
Are the atoms of sulphur in the liquid the same as the atoms in solid sulphur?
The atoms in a liquid are the same as the atoms in a solid. They are simply arranged in a different way, and have different energy and different intermolecular forces.
Do atoms of different elements have a different number of protons?
Yes, atoms of different elements have a different number of protons.
Do atoms of a different element have different numbers of protons?
Yes, atoms of different elements have a different number of protons.
Are hydrogen atoms different to oxygen atoms?
no
How can there be two different atoms of iridium?
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
Who said this atoms of differnet elements are differnet?

What kind of particle is made of different kinds of atoms?
Molecule and compound comprises of different atoms. Atoms are combined in fixed ratio.
How many different kinds of atoms are in oxygen gas?
No different ones, just Oxygen atoms.
How many different types of atoms does sugar have?
Sugar has three different types of atoms: carbon, hydrogen, and oxygen.
What are different atoms of the same element that have different atomic masses?
These atoms are called isotopes and they have a different number of neutrons.
What Molecules that are made up of different atoms are?
Molecules made up of different elements (different atoms) are called compounds.
