Element classification: Non-metal. Period number: 5. Group number: 18. Group name: Noble Gas.

Is xenon Xe a metal nonmetal or metalloid?

Xenon (Xe) exists as a colourless, odourless gas and is chemically inert. It has the atomic number 54 in the periodic table and belongs in Group 18, the Noble Gases. It is a non metal with the symbol Xe. Xenon was discovered in 1898 by William Ramsay and Morris Travers.

What type of element is xenon?

xenon (Xe), chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is colourless, odourless, and tasteless.

Is Selenium a metal nonmetal or metalloid?

Selenium is a metalloid (an element intermediate in properties between the metals and the nonmetals).

Is yttrium a metal?

A soft, silvery metal. Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation.

What are chemical properties of xenon?

Xenon is a rare, odorless, colourless, tasteless, chemically unreactive gas. It was regarded as completely inert until, in 1962, Neil Bartlett reported synthesis of xenon haxafluoroplatinate. In a gas filled tube xenon emits blue light when excited by electrical discharge.

Is xenon Reactive or nonreactive?

Xenon is a colorless, odorless, unreactive gas which liquefies at -111.7°C (161.4 K).

What is the chemical formula for xenon?

Xenon | Xe – PubChem.

Which type of ligand is Xe?

The Au−Xe bond length is 274 pm (2.74 Å). Tetraxenonogold(II) is unusual in that it is a compound of the notoriously inert atoms xenon and gold. It is also unusual in that it uses xenon as a transition metal ligand, and in that it contains gold in the +2 oxidation state.

Is antimony a metal?

Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. A lead-antimony alloy is used in batteries.

In which compound of xenon the oxidation state of xenon is 6?

Xenon trioxide is an unstable compound of xenon in its +6 oxidation state.
