This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. For broader coverage of this topic, see Boiling point . Boiling points, Master List format
The following list has substances known to be gases, but with an unknown boiling point. Fluoroamine; Trifluoromethyl trifluoroethyl trioxide CF 3 OOOCF 2 CF 3 boils between 10 and 20° [142] Bis-trifluoromethyl carbonate boils between −10 and +10° [37] possibly +12, freezing −60° [143]
Nitrogen's melting point is −210 °C and its boiling point is −196 °C. Phosphorus has a melting point of 44 °C and a boiling point of 280 °C. Arsenic is one of only two elements to sublimate at standard pressure; it does this at 603 °C. Antimony's melting point is 631 °C and its boiling point is 1587 °C.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Thorium's boiling point of 4788 °C is the fifth-highest among all the elements with known boiling points. [b] The properties of thorium vary widely depending on the degree of impurities in the sample. The major impurity is usually thorium dioxide ThO 2); even the purest thorium specimens usually contain about a tenth of a per cent of the ...
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
There is a strong correlation between higher sodium intake and higher blood pressure. [96] Studies have found that lowering sodium intake by 2 g per day tends to lower systolic blood pressure by about two to four mm Hg. [97] It has been estimated that such a decrease in sodium intake would lead to 9–17% fewer cases of hypertension. [97]
This is the longest known half-life among all radionuclides [20] and is about 160 trillion (10 12) times the age of the known universe. A further 31 artificial radioisotopes of tellurium are known, with atomic masses ranging from 104 to 142 and with half-lives of 19 days or less. Also, 17 nuclear isomers are known
