Where is most of the mass of an atom located? a. in the nucleus b. in the orbits c. in the electrons dit is split between the nucleus and the orbits

A. In the nucleus

Explanation:

Atom mainly consisting of its three subatomic particles

1) Electron

2) Proton

3) Neutron

as we know that mass of electron is given as

mass of proton and neutron is approximately same and given by

now we know that mass of electron is 10000 times smaller than the mass of neutron and proton

so major part of mass of atom is due to proton and neutron

so its whole mass is concentrated in its nucleus

correct answer would be

A. In the nucleus

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
