No it is not for astatine is the weakest of halogens and can be displaced by other lighter halogens into salts.
No. Reactivity in group 17, the halogens, decreases as you move down the group. Since astatine is lower in the group than iodine, astatine is less reactive.
I think yes it can react, if the iron is very hot. It may form Iron(III) Astatide = FeAt3
Potassium is more reactive than iodine. Together they form potassium iodide.
No it does not!
No
Francium is more reactive than potassium.
Yes, Potassium is more reactive than hydrogen.
Potassium is more reactive than sodium
Hydrogen is more reactive than Copper, but less reactive than Zinc which is less reactive than Magnesium which is less reactive than Potassium. Potassium is the most reactive of all, relatively speaking.
Bromine has more nuclear charge as compared to iodine. So, bromine easily attracts an electron and hence more reactive.
Francium is more reactive than potassium.
Yes, Potassium is more reactive than hydrogen.
KBr + I2(aq) --> KBr + I2(aq) It does not react because bromine is more electronegative and reactive than iodine.
Potassium is more reactive than sodium
Potassium
Hydrogen is more reactive than Copper, but less reactive than Zinc which is less reactive than Magnesium which is less reactive than Potassium. Potassium is the most reactive of all, relatively speaking.
Sodium
No: Potassium is much more reactive generally than silver.
Yes. Fluorine is more reactive than iodine.
Bromine has more nuclear charge as compared to iodine. So, bromine easily attracts an electron and hence more reactive.
more reactive
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
