General chemistry

A form of an element that has isotopic abundances that are different from the naturally occuring form. For example, "depleted" uranium has had most of the uranium-235 removed, and is an allobar of ...

noble gas core

Chemistry; General chemistry

All completely filled shells underneath the valence shell .

thermosetting

Chemistry; General chemistry

A polymer that solidifies on heating and cannot be remelted. The setting action results from crosslinking of the polymer chains at high temperature- a process that is not reversed by cooling and ...

concentrated

Chemistry; General chemistry

Having a relatively large amount of substance present in a unit amount of mixture. For example, a 12 M HCl solution is more concentrated than an 0.001 M HCl solution.

isotherm

Chemistry; General chemistry

A contour line that corresponds to values measured at identical temperatures. For example, curves on a plot of gas pressure measured at different volumes in a constant temperature bath are isotherms.
