Electron affinity order of halogens
WebElectron Affinity(电子亲和能） Electron affinity is the amount of energy absorbed when an electron is added to an isolated gaseous atom to form an ion with a -1 charge. Electron affinity is a measure of an atom’s ability to form negative ions. No Image 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). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar …
