Question

plz answer both of the questions ​

Answer 1

Ans.1 a unit of mass used to express atomic and molecular weights, equal to one twelfth of the mass of an atom of carbon-12.

Ans.2 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. ... The atom of an element does not exist independently.

if there is something wrong then kindly rectify it.

if you are satisfy with my ans then mark me as a brainlist.

Answer 2

Hey mate,here's ur answer:

1)ATOMIC MASS:-

The relative atomic mass (Ar)of an element is the ratio of the average mass pf an atom compared to 1/12th the mass of a carbon atom.

2)REASON WHY WE CAN'T SEE AN ATOM WITH A NAKED EYE:-

Atoms are made up of particles, such as protons,neutrons and electrons,which r soo small to be seen...Even when they combine together,they form a single atom which is also very small in size.This makes an atom invisble for the naked eye.

Hope it helps...plz mark.as Brainliest.
