Calcium - Periodic table

Calcium reacts easily with water and acids and the metal burns brightly in air, forming mainly the nitride. Uses of Calcium. Calcium forms alloys with aluminum, beryllium, copper, lead, and magnesium. It is used in the manufacture of other metals such as uranium and thorium. Calcium is used to remove oxygen, sulfur and carbon from alloys.

Biological buffers and their interactions with …

Additionally, metal complexation can be a problem in enzyme assays, since many enzymes need metal ions for maintaining their activity. Some biological buffers have very low metal-binding constants, making them excellent choices to investigate metal-dependent enzymes.

Caesium - Wikipedia

Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the syol Cs and atomic nuer 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.
