Electrons for one, and protons and neutrons are composed of quarks
He discovered that the atom contained smaller particles called electrons.
An Atom. It's the world's smallest particles of matter, atom's is known to be 20 times smaller than an average coffee bean.
Sub-atomic particles are even smaller particles that make make an atom
Well, honey, the nucleus is about 100,000 times smaller than the whole atom. It's like comparing a pea to a watermelon - one's a tiny powerhouse, and the other's just there for show. Just remember, size isn't everything, especially in the world of atoms.
an atom Actually, the smallest unit of matter is called a Quark. Quarks combine to form protons and neutrons, which are the core of an atom.
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
Atom.
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.
