The _________ contains the majority of the mass of the atom but is much ________ than the atom.
A) nucleus, smaller
B) neutrons, larger
C) electron cloud, smaller
D) pions and quarks, larger
The nucleus has almost all the mass of the atom, but only a tiny tiny tiny tiny tiny portion of the atom's volume. The rest of the atom is the electron cloud and mostly empty space.
I read that the nucleus in the middle of one atom is like a bunch of grapes in the middle of Texas !
