Last Minute Revision of Complete Chemistry Portion with full concept clarity

[@cstrainerkhanshowkat1672]

Correction, kindly correct it: The arrangement of metals as per reactivity series is: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au. The elements classified as metalloids are - boron, silicon, germanium, arsenic, antimony, and tellurium (and sometimes bismuth, polonium, and astatine).

Silicon comes under metalloid category...but in Q20 you said it's metal... correct if am wrong
