Cesium Nitride
Formula = Cs3N
The correct formula for Cesium Nitride is Cs3N. This compound is made up of one cesium ion (Cs+) and three nitride ions (N3-).
The chemical name for the chemical formula Cs3N is caesium nitride.
Yes, cesium has a metallic luster, giving it a shiny appearance.
The name phosphite is according to IUPAC reserved for PO33- ion, so Cesium phosphite would be Cs3PO3 However no compounds containing PO33- are known to exist. Hypothetical compounds containing it are often used in naming exercises by teachers/colleges/web sites. Phosphite in common use refers to HPO32- ion (IUPAC name phosphonate) and this is the formula taught in some parts of the world, cesium phosphite would therefore be Cs2HPO3
yes.
Yes, cesium is a shiny metal with a silvery-gold appearance. It has a high luster when freshly cut, but quickly tarnishes in air due to its high reactivity.
Caesium is an Alkali metal and is classed as a metal.
Cesium bromide. In a binary compound (2 constituent elements,) the non-metal becomes an "-ide" regardless of its normal name. So, oxygen becomes oxide, chlorine becomes chloride, nitrogen becomes nitride, etc...
Cs3N, would be the simplest binary compound of Cs and N. (Cs+)3 N3-
K3N is not an element. It is a compound known as potassium nitride.
