... 108. Molarity is a way to measure the concentration of a solution. Molarity is equal to the number of moles of solute divided by the number of liters of solution. The formula is on the back of the reference tables. 109. Percent by mass = mass of the part / mass of the whole x 100% 110. Parts per mil ...

... 2. Another electron from a higher energy shell in the atom jumps down to the K-shell to fill this hole, emitting an x-ray photon in the process. If the electron that jumps into the hole starts from the n = 2 (L-shell), the emitted radiation is the Ka line. If it jumps from the n = 3 (M-shell), the e ...

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.
