In addition, the strong force is also responsible for binding the quarks and gluons into protons and neutrons. So the nucleus of an atom is held together by the strong force, while the electrons are held in the atom by the electric force.

at these distances, the strong nuclear force between the protons and neutrons of a nucleus is many times stronger than corresponding electromagnetic forces (including the electromagnetic repulsion between the protons in the nucleus.)http://profmattstrassler.com/articles-and-posts/particle-physics-basics/the-structure-of-matter/the-nuclei-of-atoms-at-the-heart-of-matter/what-holds-nuclei-together/


Protons and neutrons are held together in a nucleus of an atom by the strong force. The strong force gets it name by being the strongest attractive force. It is 137 times more powerful than electromagnetic, which by the way cannot hold neutrons to protons because neutrons are not charged.

In an atom there are three fundamental forces that keep atoms together. electromagnetic force, strong force, and weak force. The electromagnetic force keeps the electrons attached to the atom. The strong force keeps the protons and neutrons together in the atom.

Ions


Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion.

Ions are atoms or molecules which have gained or lost one or more valence electrons giving the ion a net positive or negative charge.

Cations are ions with a net positive charge.

Silver: Ag+, hydronium: H3O+, and ammonium: NH4+

Anions are ions with a net negative charge.

Examples: hydroxide anion: OH-, oxide anion: O2-, and sulfate anion: SO42-

However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative. However, the reaction is still similar, whereby electrons from the anode flow to the positive terminal of the battery, and electrons from the battery flow to the cathode.
