Caesium - Wikipedia

Caesium is the softest element (it has a hardness of 0.2 Mohs). It is a very ductile, pale metal, which darkens in the presence of trace amounts of oxygen. When in the presence of mineral oil (where it is best kept during transport), it loses its metallic lustre and takes on a duller, grey appearance. It has a melting point of 28.5 °C (83.3 °F), making it one of the few elemental metals that

Reactions of Group 2 Elements with Acids - Chemistry

When a metal reacts with an acid, the metal usually reduces hydrogen ions to hydrogen gas. The elemental metal is oxidized to metal ions in the process. However, nitrate ions are easily reduced to nitrogen monoxide and nitrogen dioxide. Metals reacting with nitric acid, therefore, tend to produce oxides of nitrogen rather than hydrogen gas.

Reaction of Metals with Water, Steam and Dilute Acids

Some metals such as zinc and iron, do not react with cold water but they do react with steam. Such metals will react with steam to form metal oxide and hydrogen gas. This reaction can be easily represented by the following word equation: Metal + Steam → Metal Oxide + Hydrogen Gas. Note that a more reactive metal reacts violently with steam.

Activation Energy | Chemistry for Non-Majors

Group II metals, such as calcium, react at a much slower rate. Unlike the extremely vigorous reaction with sodium, the reaction with calcium is slow enough that we can trap the hydrogen gas released. Supplying reactant particles with energy causes the bonds between the atoms to vibrate with a …
