WebFor group 1 Alkali metals- this means that the lower down the group the less energy needed to remove an electron so the easier it is to form positive ions/ easier to react. Now what about group 7 - halogens. These atoms will want to gain an electron to form a negative ion with a full outer shell.

WebNov 7, 2015 · However, as you go down group 7 (the halogens), reactivity actually decreases, and the reason given is that it is harder for it to gain electrons, which contradicts the previous statement? Any ideas? 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. 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?

How does reactivity change as you go down a group?

WebExplaining trends in reactivity The reactivity of Group 7 elements decreases down the group. Non-metal atoms gain electrons when they react with metals. When a halogen atom reacts, it gains one electron into their highest occupied energy level (outer shell) to form a singly negative charged ion. 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.
