Answer:
A mole is just a number, like a "dozen" eggs is 12 eggs. One mole corresponds to Avogadro's number, 6.02x10^23. In chemistry, one mole of a substance means that there are 6.02x10^23 of those molecules present. A molecule is one, single, individual specimen of a compound.Atoms are the smallest invisible unit of an element. ... A mole is the unit of amount in chemistry that contains as many particles as there are atoms in exactly 12 grams of carbon-12. The bridge between atoms and moles is Avogadro's number, 6.022×1023.
PLS mark my answer as the BRAINLIEST!
ATOMS :
It is a smallest and fundamental particle of an element . An atom may not be stable due to the presence of electrons in valence shell .
MOLECULES:
Two or more atoms combine together to form molecules . molecule are formes to attain stability by losing some energy.
MOLES:
It is used to measure no of atoms , ions , molecules , etc
