consider the most stable ions which are formed by the elements sr, in, te and i. which element will form the ion with the largest radius?

i'm assuming that the correct answer is indeed the first one/ "a"..

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

lol idk man i guess u gotta ask bill nye the science guy
