Also agrees with Celsius values from Section 4: Properties of the Elements and Inorganic Compounds, Melting, Boiling, Triple, and Critical Point Temperatures of the Elements Estimated accuracy for T c and P c is indicated by the number of digits.
Aircraft must have a minimum wing area of 66 square feet (6.1 m 2), and an empty weight of 500 pounds or more. The aircraft must also have fixed landing gear, and a fixed pitch propeller. Racers compete in a 3.19-mile (5.13 km) Oval course. [3] Several aircraft were capable of meeting the specifications for Formula One at its creation.
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]
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.
The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere. log refers to log base 10 (T/K) refers to temperature in Kelvin (K) (P/Pa) refers to pressure in Pascal (Pa)

Rubidium is the second most electropositive of the stable alkali metals and has a very low first ionization energy of only 403 kJ/mol. [12] It has an electron configuration of [Kr]5s 1 and is photosensitive.
