Question

Are all atoms the same?

Answer 1

• Atoms are tiny particles which are unique to every element instead of being the same for every element.
• The presence of a different number of particles (protons, neutrons, and electrons) in an electron makes it different from the atoms of different elements. Example: Atoms of Carbon (C) are different from the atoms of Hydrogen (H).

Element	Electrons	Protons	Neutrons
Carbon (Atomic number= 6)	6	6	6
Hydrogen (Atomic number= 1)	1	1	0

• Even the atoms of the same element are different due to the difference in the number of neutrons like in isotopes.
• If we compare two elements carbon and hydrogen. They differ in mass, size and other chemical properties.
• Thus all atoms are not the same which can be defined by the different properties of the substances.

Thus all atoms are not the same.
