Isotopes: While humans have known about krypton for more than a century, there are only a few naturally occurring isotopes (forms) of krypton that were found before the 1980s one isotope takes on two forms - one stable and one radioactive. One of these is how humans discovered it in its natural state and later synthesized it. During that time, we've learned many facts about it. Humans have known about krypton for more than a century. Interesting Facts About Krypton Discovery The krypton we know and love, which does not undergo radioactive decay and does not react to other elements, is stable on Earth.

For example, a radioactive form of krypton called krypton-81 has 81 protons plus 77 neutrons for a total mass of 158 AMU (atomic mass units). The total mass of an atom determines whether it is an isotope, which is how you can determine how many neutrons there are inside an atom.
Some atoms are more massive than others therefore, they have neutrons present besides their protons. This means that a single krypton atom has 36 protons in its nucleus, and most atoms have a whole number of electrons that match their proton number. Because so few natural deposits exist, krypton gets often found in rock or soil samples in addition, given its extreme rarity within those deposits, it's difficult to measure naturally occurring amounts of krypton in Earth's atmosphere. Interesting facts about krypton boiling point is that it boils at -161 degrees Celsius (-256 degrees Fahrenheit), its melting point -111 degrees Celsius (-169 degrees Fahrenheit), and its density 3.16 grams per liter (11 pounds per cubic foot). It creates compounds with most other elements, but is resistant to attack by all acids except fluorosulfuric acid and fluorine itself. Under normal conditions, krypton occurs as colorless crystals that are both electrically and thermally conductive. Pure krypton gas (produced by fractional distillation of liquid air) is a pale yellow color, but when heated to form a plasma, it takes on a deep red hue. The color of krypton depends on how it gets used. Interesting Facts About Krypton Color, State, And Appearance In addition, scientists expect that more Earth-like planets should contain traces of krypton as well. This discovery could make studying krypton easier than before. Most attempts were unsuccessful, but volcanoes on Io (one of Jupiter's moons) produce small amounts of krypton. Most of these sources produce a tiny amount of krypton, but some researchers have tried to collect krypton from volcanic gases. We have detected it in uranium ores, in uranium extracted from seawater, and even in samples of cigarette smoke. We find native krypton only on Earth, and they thought its presence here to be extremely rare until 1971. We used krypton in lights before tungsten came about, and today, it's most commonly used in lasers and plasma televisions. It was first discovered by English chemist William Ramsay in March 1894, who found it as an impurity in liquid air and hence named it after the Greek word kryptos, meaning hidden or secret, since they detected indirectly it with its release of nitrogen gas. What interesting facts about krypton do you know? Krypton is the lesser-known chemical element in group 18 on the periodic table of elements.
