The furthest point an orbiting body gets from its attracting mass. Whilst this term can also be used instead of Aphelion (i.e. it means the same thing), it is normally used to describe the point at which the distance between the earth and its orbiting moon is greatest This term is made up of the Greek prefix ap for ‘away from’ or ‘farthest point’, and the Greek word gee for the earth.

Evidence for pi stacking. The benzene dimer is the prototypical system for the study of pi stacking, and is experimentally bound by 8–12 kJ/mol (2–3 kcal/mol) in the gas phase with a separation of 4.96 Å between the centers of mass for the T-shaped dimer. The small binding energy makes the benzene dimer difficult to study experimentally, and the dimer itself is only stable at low.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. [better source needed] For many molecules, the sharing of electrons allows.

If the electronegativity difference between the two atoms is above 1.7, then ionic. The bonds you're talking about are ionic, polar covalent and pure covalent.
