Which of the following arrangement of elements is in decreasing order of electronegativity?

A. Na, Mg, Al, Si, P
B. Na, A1, Mg, P, Si
C. P, Mg, Na, Si, Al
D. P, Si, Al, Mg, Na

Correct Answer:

Option D = P, Si, Al, Mg, Na

Explanation

– Reactivity series is K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Hg > Ag > Au.

-Very Electropositive Metals Most active metals have low electronegativities
