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 ...
The word unobtainium derives humorously from unobtainable, with -ium, a suffix for chemical element names. It predates the similar-sounding systematic element names, such as ununennium, unbinilium, unbiunium, and unbiquadium. An alternative spelling, unobtanium, is sometimes used, by analogy to the names of real elements like titanium and uranium.
Organic compounds have one or more carbon atoms that are bound to other elements, usually hydrogen, oxygen, nitrogen and sulfur. All life on Earth is based on carbon and is built from organic ...
The minerals detected included sodium carbonate compounds such as trona (sometimes referred to as “soda ash”) that the scientists said had never been observed in other extraterrestrial samples.
Promethium is the only lanthanide and one of only two elements among the first 82 with no stable or long-lived isotopes. This is a result of a rarely occurring effect of the liquid drop model and stabilities of neighbor element isotopes; it is also the least stable element of the first 84. [4]
A new Clean Label Project report suggests some protein powders contain heavy metals lead and cadmium. See which ones are safe here, plus what an expert advises.
Livermorium is expected to be near an island of stability centered on copernicium (element 112) and flerovium (element 114). [ 85 ] [ 86 ] Due to the expected high fission barriers , any nucleus within this island of stability exclusively decays by alpha decay and perhaps some electron capture and beta decay . [ 4 ]
