cerium

Cerium is a chemical element with an atomic number of 58.

The element cerium, discovered in 1803, was named after the asteroid.

This means that the nucleus of Cerium has 58 protons in it.

Cerium is named for the asteroid Ceres, both having been discovered the same year (1801).

All but 16 isotopes of cerium have half-lives greater than 1 second.

There is almost no cerium in the atmosphere.

However, very little cerium accumulates in the food chain.

There is a total of 40 milligrams of cerium in a typical 70-kilogram human.

Humans typically consume less than a milligram per day of cerium.

Doped with cerium, it is used as a scintillator material.

It was added as a mix with cerium oxide.

Cerium is not often used as a metal since it quickly reacts with the air and tarnishes.

Cerium is also used in special glass, ceramics and self cleaning ovens.

Cerium, iron, manganese and nickel are also used, although each has its own limitations.

Cerium is a silvery metal, belonging to the lanthanide group.

This effect is suppressed by addition of cerium oxide.

My cerium oxide is a moderate dark orange color.

Cerium is sometimes used in alloys because it often makes the alloy more heat resistant.

Large ore bodies of the cerium earths can be found around the world and are being exploited.

The low temperature behavior of cerium is complex.

It may contain cerium substituting in the calcium position.

There are four isotopes of cerium that occur naturally.

In particular, cerium oxide is added into diesel fuels.

Cerium, like all rare-earth metals, is of low to moderate toxicity.

Berkelium and cerium are then separated with another round of ion-exchange treatment.
