Answer:
Matching the elements to the appropriate blanks as follows :
1) The element that would most effective at accepting electrons is ; CI
2) The element that would be the best insulator is ; Cl
3) The element best to form an ionic compound with sulfur is ; Rb
The acceptance of electrons by elements depends on the electronegativity of the element. from the options listed the element with the highest level of electronegativity is Cl ( chlorine ) therefore it the most effective at accepting electrons
Cl ( chlorine) is a non metal and non-metals are semi-conductors or insulators. therefore Cl would act as the best insulator when compared to other elements.
when metals react with non-metals they form an ionic compound. for sulfur the best metal to react with it is Rb ( soft silvery metal ) and the reaction of Rb and sulfur in hydrogen gas. results in Rb₂S₅
Hence we can conclude Matching the elements to the appropriate blanks as follows : The element that would most effective at accepting electrons is ; CI, The element that would be the best insulator is Cl ,The element best to form an ionic compound with sulfur is ; Rb
