Question #c0a6c
1 Answer
Yes.
Explanation:
An atom is composed of a nucleus (protons and neutrons) and one or mores electrons.
See table:
The distance between nucleus and electron cloud is very large! See figure below:
Compare the mass of the electron with those of the proton and the neutron. The protons and the neutrons have a much higher mass and are concentrated in the nucleus.
Therefore, the mass of the atom is practically concentrated in its nucleus.
