If positive and negative charges are both present in equal amounts, then this is the isoelectric point. Thus, the PZC refers to the absence of any type of surface charge, while the IEP refers to a state of neutral net surface charge. The difference between the two, therefore, is the quantity of charged sites at the point of net zero charge.

The largest size of minivans is also referred to as "large MPV" and became popular following the introduction of the 1984 Renault Espace and Dodge Caravan. Since the 1990s, the smaller compact MPV and mini MPV sizes of minivans have also become popular. If the term "minivan" is used without specifying a size, it usually refers to a large MPV.
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]

The principle of the electron was first theorised in the period of 1838–1851 by a natural philosopher by the name of Richard Laming who speculated the existence of sub-atomic, unit charged particles; he also pictured the atom as being an 'electrosphere' of concentric shells of electrical particles surrounding a material core.
