Which of the following arrangement of elements is in decreasing order of electronegativity?
Na, Mg, Al, Si, P
Na, A1, Mg, P, Si
P, Mg, Na, Si, Al
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
