Which component of the atom has the least mass

The correct answer is: Electron

Explanation:

Atom is the fundamental unit of matter that is composed of the subatomic particles electrons, protons and neutrons.

The nucleus of an atom contains protons and neutrons and are collectively known as the nucleons. Approximately 99.94% of the total mass of the atom is in the nucleus on the atom.

Therefore, the electrons has the least mass of about 9.11×10⁻³¹ kg which is approximately 1/1836 to the mass of the proton.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
