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.

An electron is not the largest part of an atom. An electron is the smallest component of an atom. Relatively, if a neutron or proton were 1 unit in size, an electron would be 1/1840 units in size.
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.

Electron
The smallest particle in the atom is the electron.
Out of protons, neutrons, and electrons, electrons are the smallest.
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.
