Answer 1

HERE ARE YOUR QUESTIONS :-

1. DEFINE THE ATOMIC MASS UNIT.
2. WHY IS IT NOT POSSIBLE TO AN ATOM WITH NAKED EYES?
3. WHAT IS MOLICULE?

(its naked not nacked )

HERE ARE ANSWERS FOR YOU :-

1st) ans)

A Dalton, also known as an atomic mass unit, is roughly the mass of a single proton or neutron. Protons and neutrons have masses of approximately 1 atomic mass unit each, whereas electrons only have a mass of. 0006 amu.

2nd) ans)

It is not possible to see an atom with naked eyes because the size of an atom is very very small. We can see the atom only under the microscope. Its atomic radius is 10^-10 m. The atom of an element does not exist independently.

The dimension of atoms is very small of the order of 1 mm.

3rd) ans)

Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
