Reactivity going down group 7
WebReactivity of group 7 non-metals decreases as you go down the group As you go down group 7, the number of shells of electrons increases, the same as with all other groups … WebWhy does reactivity decrease going down group 7? As you go down group 7, the outershell electrons are further away from the nucleus. This causes a weak attraction between them …

WebSep 9, 2014 · The reactivities of the halogens decrease down the group ( At < I < Br < Cl < F). This is due to the fact that atomic radius increases in size with an increase of electronic energy levels. This lessens the attraction for valence electrons of … WebJan 30, 2024 · As you go down a group, electronegativity decreases because the bonding pair of electrons is increasingly distant from the attraction of the nucleus. Consider the hydrogen fluoride and hydrogen chloride molecules: The bonding pair is shielded from the fluorine's nucleus only by the 1s 2 electrons.

WebProperties of the group 7 elements. As you go down the halogens, from fluorine to astatine, the elements become darker in colour and have a higher boiling point. ... Unlike the group 1 metals, reactivity decreases as you go down the halogens. This means that fluorine, at the top of the group, is the most reactive. ... Webas you go down the group. Flowchart explaining why reactivity increases down Group 1 Flowchart adapted from: K. Taber, Chemical misconceptions – prevention, diagnosis and cure, London: Royal Society of Chemistry, 2002 Activity 1 Construct a similar flowchart to explain why the Group 7 elements get less reactive as they go down the Group.
WebMay 27, 2024 · Reactivity of Group 7 non-metals increases as you go up the group. Out of the 3 halogens, chlorine, bromine and Iodine, chlorine is the most reactive and iodine is the least reactive. Is Group 1 or group 7 more reactive? As you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive.
WebReactivity decreases down the group. This is because group 7 elements react by gaining an electron.
