Covalent Bonds. Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds.
The resulting ions of opposite charge lower their energy by moving close to one another. The interaction between the two interacting ions is called an ionic bond, and NaCl is an ionic compound. We will assume that all compounds between metals and nonmetals are ionic. However, recall that late metals (those that lie to the.

Ionic Solids. When cations and anions precipitate out of a saturated solution they crystallize into a lattice arrangement that maximizes the attractive forces between cations and anions while minimizing the repulsive forces between ions of the same charge. For example, shown below is the arrangement of ions found in.

Ionic Bonds – Weak or Strong? (thanks for asking!) This "discussion" stemmed from a question asked by a student who was taking organic and cell bio at the same time. In cell bio, the student was told that ionic bonds are very weak. But in organic lecture, the student was told that a strong Li-O ionic bond helped drive a.

What makes diamond the hardest substance in the world and graphite—the stuff of pencil lead—comparatively so soft? Both are made of nothing but carbon atoms. The answer lies in the chemical bonds among those atoms and how they.
The nature of atom-bound electrons, as we have seen, makes the ionic forms of some atoms much more energetically stable—and thus more common—than the neutral form. For example, we saw that inert gas atoms don't tend to form ions because they have a full octet of electrons in their outer shell. Halides (F, Cl, Br, I, At).

Short version: We don't call bonds "physical", there are chemical bonds and other types of interactions between particles. The chemical bonds are classified this way because they make up molecules, salts, polymers and such, which are the materials chemists are interested in studying, and not particularly.

Ionic bonds are formed during attraction of two ions of opposite charge involving electrostatic force. Ionic bonds hold a strength varying between 5 and 10 kcal/mol in an aqueous environment. The strength of ionic bonds tends to decrease as two participating atoms are taken apart, and this decrease has been observed to.
