electrons
The lightest atom is hydrogen. It consists of a single proton and an electron, making it the simplest and lightest element on the periodic table.
The lightest subatomic particle of an atom is the electron. It has a very small mass compared to protons and neutrons, making it a key component in determining the chemical properties of an atom.
The lightest atom is hydrogen, and its symbol is H.

The lightest of an atom's main constituents is the electron. Electrons have a very small mass relative to protons and neutrons, and they orbit the nucleus of an atom.
The lightest particle in the atom is the electron.
Hydrogen is the lightest chemical element; the chemical symbol is H.
The lightest and smallest atom is hydrogen. It has a single proton and a single electron. There are some other isotopes of hydrogen that have one or more neutrons. Although those isotopes are naturally occurring, they are rare and for most purposes, we can ignore their existence.
Depends, but it is probably electron
In the atom the electron is the lightest.
The electron is the lightest of the three particles that make up an atom, with a mass of approximately 9.11 x 10^-31 kilograms.
