Neptunite is a silicate mineral with the formula K Na 2 Li(Fe 2+, Mn 2+) 2 Ti 2 Si 8 O 24. With increasing manganese it forms a series with mangan-neptunite . Watatsumiite is the variety with vanadium replacing the titanium in the formula.
Neptunium compounds are compounds containing the element neptunium (Np). Neptunium has five ionic oxidation states ranging from +3 to +7 when forming chemical compounds, which can be simultaneously observed in solutions.

Benitoite typically occurs with an unusual set of minerals, along with minerals that make up its host rock. Frequently associated minerals include: natrolite, neptunite, joaquinite, serpentine and albite. Benitoite is a rare mineral found in very few locations including San Benito County, California, Japan and Arkansas.

A human touching or handling eggs or baby birds will not cause the adult birds to abandon them. [55] The same is generally true for other animals having their young touched by humans as well, with the possible exception of rabbits (as rabbits will sometimes abandon their nest after an event they perceive as traumatizing).
In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive.From a thermodynamic perspective, a substance is inert, or nonlabile, if it is thermodynamically unstable (positive standard Gibbs free energy of formation) yet decomposes at a slow, or negligible rate.
