Answer 2

STEP 1 : To write the formula of sodium oxide , we need to write the symbol for Sodium and oxide ions along with their charges.

Na +¹ 0²-

There is no common factor in the number corresponding to their charges we will now crisscross their charges,

=> Na+¹ 0²- ( When They are written as crisscross method = Na2O
