Cerium Specification

The Cerium, with the CAS registry number 7440-45-1, is also known as UNII-30K4522N6T. It belongs to the product categories of Inorganics; Catalysis and Inorganic Chemistry; Cerium; Cerium Metal and Ceramic Science; Chemical Synthesis; Metals. Its EINECS number is 231-154-9. This chemical's molecular formula is Ce and molecular weight is 140.12. What's more, its systematic name is Cerium. This chemical is an element of the rare earth family of metals. It is a soft, silvery, ductile metal which easily oxidizes in air. Cerium is the most abundant of the rare earth elements, making up about 0.0046% of the Earth's crust by weight. It is found in a number of minerals, the most important being monazite and bastnasite. Cerium is a malleable metal used in industrial applications.

When you are using this chemical, please be cautious about it as the following:
This chemical is highly flammable, so you should keep it away from sources of ignition - No smoking. It is harmful by inhalation, in contact with skin and if swallowed. It is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it, you need wear suitable protective clothing, gloves and eye/face protection.

You can still convert the following datas into molecular structure:
(1)SMILES: [Ce]
(2)Std. InChI: InChI=1S/Ce
