Components of the atom are protons, neutrons and electrons.
An atom is smaller.
The neutron is a part of the atom, therefore it is smaller.
The Universe was never smaller than an atom.
smaller
An atom is smaller than a compound because if an electron fits in an atom, and an atom is a part of a compound, it means a compound is bigger than an atom
an atom is about a trillion times smaller then a speck of dust.
Neutrons, protons, and electrons make up an atom, so they are smaller.
An atom is smaller than a cell, and a molecule is smaller than both atoms and cells. Cells are composed of molecules, which in turn are made up of atoms.
Smaller
A proton is smaller than a molecule, which is a group of atoms bonded together. The nucleus is smaller than both a molecule and an atom, as it is the central part of an atom where most of its mass is concentrated.
Atom.
Electrons are one of the things that make up an atom. So an electron is smaller.
