Is Magnesium a cation or anion?

Magnesium is a group 2 metal Es forms cations with a stable noble gas electron configuration when it loses its two valence electrons. Bromine forms a stable noble gas electronic configuration when it gains an electron. So we find magnesium as a 2+ cation and bromine as a 1- anion in a 1:2 ratio in the compound.

What is Cs in chemistry?

Cesium (IUPAC notation) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28.5 °C (83.3 °F), giving it to one of the makes only five elemental metals that are liquid at or near room temperature.

How dangerous is cesium?

Stable cesium is not likely to affect children’s health, but large amounts of gamma radiation from sources such as radioactive cesium could damage cells and possibly cause cancer as well. Brief exposure to extremely large amounts of radiation can cause nausea, vomiting, diarrhea, hemorrhage, coma, and even death.
