Its melting point of 180.50 °C (453.65 K; 356.90 °F) [13] and its boiling point of 1,342 °C (1,615 K; 2,448 °F) [13] are each the highest of all the alkali metals while its density of 0.534 g/cm 3 is the lowest. Lithium has a very low density (0.534 g/cm 3), comparable with pine wood. [14]
Hydrogen, like the alkali metals, has one valence electron [122] and reacts easily with the halogens, [122] but the similarities mostly end there because of the small size of a bare proton H + compared to the alkali metal cations. [122] Its placement above lithium is primarily due to its electron configuration. [157]

From the weight of the sodium salt and the volume of air in the room, we easily calculate that one part by weight of air could not contain more than 1/20 millionth weight of sodium. Occurrence The Earth's crust contains 2.27% sodium, making it the sixth most abundant element on Earth and the fourth most abundant metal, behind aluminium , iron ...

For a metal, zinc has relatively low melting (419.5 °C, 787.1 °F) and boiling points (907 °C, 1,665 °F). [8] Cadmium is similar in many respects to zinc but forms complex compounds. [ 16 ] Unlike other metals, cadmium is resistant to corrosion and as a result it is used as a protective layer when deposited on other metals.
