Webhalogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). … WebBeryllium is relatively unreactive but forms many covalent compounds, whereas the other group members are much more reactive metals and form ionic compounds. As is the case with the alkali metals, the heaviest element, radium, is highly radioactive, making its size difficult to measure.
The most reactive metals are located in which area of the …
Webrubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre. Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after the two prominent red lines of its spectrum. WebFluorine is a halogen on the periodic table that belongs to Group 17, and the halogens are the most reactive. When it comes to this, which periodic table family is the most reactive, fluorine is a halogen. Alkali metals are the most reactive metals in periodic tables, followed by alkaline earth metals. camping near london ky

Web23 jan. 2024 · The two most reactive families of elements are the halogens and the alkali metals. Which chemical is most reactive? fluorine The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal (and most expensive element). Web30 apr. 2024 · The most reactive metal is francium, the last alkali metal (and most expensive element). The least reactive elements are the noble gases. What is the most … WebWhat's more, to the surprise of most chemists and going against the well-known trends of the periodic table, it turns out that francium is not the most reactive metal. On descending a group in the periodic table, on average the outermost electrons get further and further away from the nucleus and as a result, become easier to remove from the atom. fis7水中胶
