elytron

n : either of the horny front wings in beetles and some other

insects which cover and protect the functional hind wings

[syn: {wing case}]

electron

A sub-atomic particle with a negative quantised

{charge}. A flow of electrical {current} consists of the

unidirectional (on average) movement of many electrons. The

more mobile electrons are in a given material, the greater it

electrical conductance (or equivalently, the lower its

resistance).
