WebThe halogens generally show many of the properties typical of non-metals. They are poor conductors and have low melting and boiling points. Halogen ions are called halides and are usually negative ions with a charge of -1. Reactivity and electronegativity decrease as you go down the group whilst atomic radius and melting and boiling point increase. WebChemistry questions and answers. Why are the halogens among the most active nonmetals? Their valence electrons are more effectively shielded. Their d orbitals are completely filled. They only need one electron needed to attain a nobel gas configuration They all have smaller diameters than other nonmetals. ООО All halogens have low …

WebThe group 7 elements are all reactive non-metals. They react with metals to form metal halides, and with hydrogen to form acidic hydrogen halides. Reactivity decreases down the group. WebMar 6, 2016 · Chlorine. The most active nonmetal in any period is second to last (halogens), right before the noble gases. Atoms tend to give electron (metals) or take them (nonmetals) to achieve a stable configuration such as a noble gas (like argon) already has.
