Question

astatine is the element below iodine in group 7? would you expect astatine to be more or less reactive? give a reason

Answer 1

Answer:

I think it would be less reactive and you should believe too. It is the least reactive of the halogens. It also has metallic properties, showing why this happens. It is also highly radioactive. The only compound created using astatine to date is hydroastatic acid.
