What is the 58th element?

Cerium – Element information, properties and uses | Periodic Table.

What is the flammability of cerium?

Specific Hazards Arising from the Material: Cerium sparks with friction and will burn under fire conditions. May react with water under fire conditions liberating flammable hydrogen gas. May emit fumes of cerium oxide under fire conditions.

What is Sulphur used for?

Sulfur is used in the vulcanisation of black rubber, as a fungicide and in black gunpowder. Most sulfur is, however, used in the production of sulfuric acid, which is perhaps the most important chemical manufactured by western civilisations.

What is praseodymium for?

Praseodymium is used in a variety of alloys. The high-strength alloy it forms with magnesium is used in aircraft engines. Mischmetal is an alloy containing about 5% praseodymium and is used to make flints for cigarette lighters. Praseodymium is also used in alloys for permanent magnets.

What is the element of PA?

protactinium
protactinium (Pa), radioactive chemical element of the actinoid series of the periodic table, rarer than radium; its atomic number is 91. It occurs in all uranium ores to the extent of 0.34 part per million of uranium. Its existence was predicted by Russian chemist Dmitry Mendeleyev in his 1871 periodic table.

Why is curium special?

Curium is the most radioactive element that can be isolated. It is so intensely radioactive that it boils water, making its chemistry difficult to study. It also glows in the dark (see right). Curium was first intentionally synthesised in 1944 by a team of chemists led by Glenn Seaborg.

What does cerium mean?

• CERIUM (noun) The noun CERIUM has 1 sense: 1. a ductile grey metallic element of the lanthanide series; used in lighter flints; the most abundant of the rare-earth group. Familiarity information: CERIUM used as a noun is very rare.

Is cerium a transition element?

TRANSITION ELEMENT: LANTHANIDE . Cerium was discovered by Jöns Jakob Berzelius and Wilhelm Hisinger (SE) in 1803 and independently by Martin Heinrich Klaproth (DE). Named after the asteroid Ceres discovered two years before the element. It is a malleable, ductile, iron-grey metal that tarnishes in air and reacts easily with water.

Is cerium a conductor?

Cerium is a fairly good conductor of heat, but a poor conductor of electricity, its resistance being 71.6 micro-ohms per cm. cube at the ordinary temperature. The following values have been obtained for the specific heat: -. temp. range. spec. ht.

What is number of cerium?

Cerium is a chemical element with an atomic number of 58. This means that the nucleus of Cerium has 58 protons in it. The atomic mass of Cerium is 140.12. The Chemical symbol of Cerium is Ce and it is a member of the Lanthanide group.
