Is astatine or iodine more reactive
Webastatine (1) At. Group 17 elements are also known as: (a) halogens (2) (name still in common use) (b) Group VIIA (name no longer used) Group 17 elements are non-metals. Group 17 elements exist as diatomic molecules (X 2) when not combined with other elements. Group 17 elements can combine with nearly all the elements in the periodic table. WebDown the group reactivity decreases in the case of non-metals. This is because down the group size increases and the tendency to pull electrons towards the nucleus decreases. As a result electronegativity decreases and then reactivity also decreases. Reason for less reactive Iodine. Iodine contains five shells, whereas B romine has four.

A piece of magnesium ribbon is added to hydrogen chloride in three separate experiments WebChlorine will displace bromine or iodine from an aqueous solution of the metal halide: Cl 2 + 2KBr → 2KCl + Br 2. chlorine + potassium bromide → potassium chloride + bromine. Cl 2 + 2KI → 2KCl + I 2. chlorine + potassium iodide → potassium chloride + iodine. Bromine with Iodides. Bromine is above iodine in group 7 so it is more reactive
WebAstatine is the 85th element of the periodic table with a symbol ‘At’. It is a radioactive element and is said to be the most heavier among the halogens. This element exhibits similar chemical properties that of the element iodine. The isotopes of astatine have a short life of about 8.1 hours, and some isotopes are said to be unstable.
