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. [15]: 382 Due to its strong electropositive nature, rubidium reacts explosively with water [16] to produce rubidium hydroxide and hydrogen ...
Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals and is never found in nature as a free element. 89 Y is the only stable isotope and the only isotope found in the Earth's crust. The most important present-day use of yttrium is as a component of phosphors, especially those used in LEDs.
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [ 3 ]
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 ...
Hydrogen bromide – HBr [171] Hypobromous acid – HOBr [172] Iodine monobromide – IBr [173] Iron(II) bromide – FeBr 2 [174] Iron(III) bromide – FeBr 3 [175] Lead(II) bromide – PbBr 2 [176] Lithium bromide – LiBr [177] Magnesium bromide – MgBr 2 [178] Mercury(I) bromide – Hg 2 Br 2 [179] Mercury(II) bromide – HgBr 2 [180] [181 ...
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
The average adult has a blood volume of roughly 5 litres (11 US pt) or 1.3 gallons, [10] which is composed of plasma and formed elements. The formed elements are the two types of blood cell or corpuscle – the red blood cells, (erythrocytes) and white blood cells (leukocytes), and the cell fragments called platelets [12] that are involved in ...
