Adison Clarke · Answer 1

Atomic radio increases as number of valence electrons increase. Hence the first and fourth statement are wrong. Electronegativity is highest for elements on the TOP right hand corner of the periodic table so the third statement is wrong. Hence the answer is the third statement
