Zirconium is commonly used as the a great cladding to possess nuclear reactor fuels. Rare metal features a great melting section away from 1772 levels C, the brand new boiling point away from 3827 +/- one hundred degree C, this the law of gravity from 21.forty five (20 stages C), with an excellent valence of 1, dos, step 3, or cuatro. It doesn’t oxidize in the air any kind of time temperatures, though it is actually corroded from the cyanides, halogens, sulfur, and you will caustic alkalis.

Xenon is actually a substance feature with nuclear count 54 which means you will find 54 protons and you can 54 electrons regarding the atomic design. Iodine are a chemical feature which have nuclear amount 53 which means that you’ll find 53 protons and you can 53 electrons on the nuclear design. Tellurium are a chemical function which have atomic number 52 and therefore you’ll find 52 protons and you will 52 electrons in the atomic framework. Antimony is a substance feature with atomic amount 51 and therefore there are 51 protons and you will 51 electrons from the nuclear design.
