An Atom contains both Protons & Electrons, and sometimes even Neutrons. An Electron is about 1/1840th the mass of a Proton or a Neutron, so Atoms are definitely much heavier.
The atom that is smallest in size is the hydrogen atom.
Hydrogen is the smallest atom because it has only one proton and one electron, resulting in the simplest atomic structure. The size of an atom is mainly determined by the number of protons in its nucleus. Since hydrogen has the fewest protons among all elements, it is the smallest atom.
Smallest to Largest.. - Electron - Proton - Atom - Compound - Molecule
No, electrons are not the largest particles in an atom. Electrons are the smallest subatomic particles in an atom, found in the electron cloud surrounding the nucleus. The nucleus, which contains protons and neutrons, is much larger in comparison to the electrons.
The electron is most responsible for the size of an atom because it occupies the space around the nucleus in electron clouds. The number of electrons and their energy levels determine the size of an atom.
electron is the smallest
The atom that is smallest in size is the hydrogen atom.
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
In the atom the electron is the smallest.

The smallest particle in the atom is the electron.
The smallest of the 3 particles in an atom is the electron. Electrons have a negligible mass compared to protons and neutrons, and they orbit the nucleus of an atom in discrete energy levels.
Hydrogen is the smallest atom because it has only one proton and one electron, resulting in the simplest atomic structure. The size of an atom is mainly determined by the number of protons in its nucleus. Since hydrogen has the fewest protons among all elements, it is the smallest atom.
You probably mean the smallest part of an atom. That would be an electron, because electrons are the particles making up atoms that are smallest in size.
The smallest atom is hydrogen.
