... Bonds are polar when one atom is positive and the other negative. Molecules with many atoms have polarity, with one end positive, the other negatively charged. You can predict the polarity of the molecule by looking at the ends of the molecule to see if it has a positive end and a negative end. Lone ...

Electronic Properties of Metals
... Assumptions of the FEG Model 1. Metals have high electrical conductivity and no apparent activation energy, so at least some of their electrons are “free” and not bound to atoms 2. Coulomb potential energy of positive ions U 1/r is screened by bound electrons and is weaker at large distances from ...

Ionization
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. Ionization can result from the loss of an electron after collisions with sub atomic particles, collisions with other atoms, molecules and ions, or through the interaction with light. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected.
