Reactivity down group 7

WebReactivity decreases down the group. This is because group 7 elements react by gaining an electron . As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus. Does electronegativity increase down group 1? http://passmyexams.co.uk/GCSE/chemistry/trends-in-halogens.html

WebDec 21, 2024 · The melting points and boiling points of the halogens increase going down group 7. This is because, going down group 7: the molecules become larger. more energy is needed to overcome these forces. What is the trend in reactivity as you go down group 7? Reactivity decreases down the group. WebIn each case, a halogen higher in the Group can oxidise the ions of one lower down. For example, chlorine can oxidise the bromide ions (in, for example, potassium bromide solution) to bromine: Cl 2 + 2Br - 2Cl - + Br 2. The bromine appears as an orange solution. As you have seen above, chlorine can also oxidise iodide ions (in, for example ... razar family partnership https://creationsbylex.com

WebThe fall in reactivity is because the halogens become less good oxidising agents as you go down the group. In the cases of chlorine and bromine, the iron atoms are oxidised to iron (III) ions. Electrons are removed by the chlorine or bromine. Fe Fe 3+ + 3e - But with iodine you only get iron (II) ions. Fe Fe 2+ + 2e - WebThe halogens are non-metals and when non-metals react with metals, they GAIN the electrons that the metals lose. As you move down group 7, the atomic radius get bigger (more protons, more electrons, more shells) and so the negatively charged electrons in the outer shell move further away from the positively charged nucleus.
