The CORRECT order of increasing radii of the elements Na, Si, Al and P

1.	The CORRECT order of increasing radii of the elements Na, Si, Al and P is …………… (A) Si < Al < P < Na (B) Al < Si < P < Na (C) P < Si < Al < Na (D) Al < P < Si < Na
Answer» Correct option is: (C) P < Si < Ai < Na As we move along a period from left to right the radii of element decrease. Na, Si, Al and P are third period elements Therefore, the order of radii is Na > Al > Si > P (C) P < Si < Al < Na

The CORRECT order of increasing radii of the elements Na, Si, Al and P is …………… (A) Si < Al < P < Na (B) Al < Si < P < Na (C) P < Si < Al < Na (D) Al < P < Si < Na

Answer»

Correct option is: (C) P < Si < Ai < Na

As we move along a period from left to right the radii of element decrease. Na, Si, Al and P are third period elements

Therefore, the order of radii is Na > Al > Si > P
