WebApr 6, 2024 · The reactivity of halogen towards halogen decreases as we move down group 17. Therefore, their acidity also decreases as we move down the group. In dark H₂ + F₂→ 2HF In sunlight H₂ + Cl₂ → 2HCl Δ H + Br₂ → 2HBr Δ H₂ + I₂ → 2HI Reaction with Oxygen Halogen combines with oxygen to form halogen oxides, but they are not steady. WebJul 5, 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. Which is more reactive bromine or iodine in Group 7? Bromine is above Iodine in Group 7 so is more reactive.
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. ... 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 and makes it difficult to attract an electron to complete the outer shell. What are the Halogens? Fluorine, Chlorine, Bromine, Iodine, Astatine What do halogens react with? WebAs we move down in group 1, the atomic radius increases and ionisation energy decreases. Both these factors make losing the outermost electron easy and hence chemical reactivity …
