When atoms approach one another, their nuclei and electrons interact and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative. Ionic compounds dissolve in water easily, when they do this their lattice breaks up completely and water molecules surround the seperated ions. chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. A cube of tightly packed alternate metal and non-metal ions. This is a regular repeating arrangement of metal and non-metal ions which creates compounds with very high melting points which conduct when molten or in solution but never when solid. Ionic compounds form what is known as a lattice structure. When these two charged particles come together they form an ionic bond because the positive magnesium ion is attracted to the negatively charged chloride ion.

To become stable it must gain an electron to obtain a full outer energy level. Non-metals form negative ions because they gain electrons to become stable.Ĭhlorine (Cl) has an electron arrangement 2,8,7.

They change into ions with a two positive charge.

To become stable it must lose its two outer electrons to obtain a full outer energy level.Ītoms are neutral because they have equal numbers of protons and electrons however, when they lose two electrons they are no longer neutral. Magnesium (Mg) has the electron arrangement 2,8,2. Metals form positive ions because they lose electrons to become stable. The ionic bond is the electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion. Ionic bonds are formed between a metal and non-metal, for example sodium chloride.Īn atom of sodium will lose an electron and form a positive ion.Īn atom of chlorine will gain an electron and form a negative ion. Learn about the basic structure of an ion, related to atomic number and mass.
