What ions are held together by strong mutual attraction?

Answer 1

In ionic bonding, an attraction is formed between a cation (which easily gives up an electron to be positive) and an anion (which easily accepts an electron to be negatively charged). An electrostatic coulomb attraction force is then felt between the two ions, holding them together (positive and negative charges attract). It should be noted that no protons are exchanged in the formation of an ion. The cation has an overall positive charge because the removal of electrons has exposed the positive charge of the nucleus. Anions seek greater stability through gaining electrons, completing the nearly-filled valence shell. Therefore, the coulomb attraction is actually between unscreened protons from the cation and the overcompensating electron cloud surrounding the anion.

Answer 2

Ionic bonds are formed between ions with opposite charges due to strong mutual attraction. For example, a cation (positively charged ion) is attracted to an anion (negatively charged ion), leading to the formation of an ionic bond. This attraction is due to the electrostatic force between the opposite charges of the ions.

adhesive for with others cohesive for with themselves

Answer 4

Gluon, it's a quanta of the strong nuclear force which is the strongest force in this universe next to the weak nuclear force (bosons), electromagnetism (photons) and gravity (gravitons).
