Question

A probe sent to the planet mercury has measured the electronegativities of several elements it has detected on the planet. element 1 2 3 4 5 electronegativity, χ 2.58 1.88 2.10 2.60 3.16 which element would you expect to identify as a metal?

Answer 1

A metal is one which ionizes easily and gives electrons whencompared to other elements. So it should have a lower ionization energy. Hence we would expect element 2 to be a metal.
