Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
most of an atoms is taken up by
8x10^-15-1x10^-12
Most of the mass is in the nucleus; most of the volume is in the electron "cloud".
An electron weighs about 1/1836 of a proton, so as far as an atom is concerned, all the mass is in the nucleus, with the protons and neutrons. But the electrons are rotating in their orbits a long way (in proton size terms) from the nucleus. So most of the volume of an atom is empty space.
true
The thing that takes up the most space of an atom at about 99.99% of the size of the atom is empty space. The majority of the remaining 0.01% is found in the nucleus and about 0.00001% of the atom is taken by the electrons.
