Answer

Answer:

  1. Lithium reacts with oxygen to produce lithium oxide ($Li_2O$).
  2. Beryllium reacts with oxygen to produce beryllium oxide ($BeO$).

Explanation:

Step1: Analyze lithium - fluorine reaction

Lithium ($Li$) has a +1 charge and fluorine ($F$) has a -1 charge. The correct formula for lithium fluoride is $LiF$, not $LiF_2$.

Step2: Analyze lithium - oxygen reaction

Lithium has a +1 charge and oxygen ($O$) has a -2 charge. To balance the charges, 2 lithium atoms are needed for every oxygen atom, so the formula is $Li_2O$.

Step3: Analyze beryllium - fluorine reaction

Beryllium ($Be$) has a +2 charge and fluorine has a -1 charge. The correct formula for beryllium fluoride is $BeF_2$, not $BeF$.

Step4: Analyze beryllium - oxygen reaction

Beryllium has a +2 charge and oxygen has a -2 charge. The formula for beryllium oxide is $BeO$ as the charges balance 1:1.

Step5: Analyze boron - fluorine reaction

Boron ($B$) has a +3 charge and fluorine has a -1 charge. The correct formula for boron fluoride is $BF_3$.
