Question

students in a chemistry class are using the periodic table to predict how elements will react with one another. what compound forms from a synthesis reaction between lithium (li) and oxygen (o)? select the product and the type of bonds that form. a. lio₂ b. 2 lio c. li₂o d. covalent e. ionic f. metallic

Explanation:

Step1: Determine lithium's charge

Lithium (Li) is in Group 1 of the periodic table and has a +1 charge ($Li^+$) when it forms an ion.

Step2: Determine oxygen's charge

Oxygen (O) is in Group 16 of the periodic table and has a - 2 charge ($O^{2 -}$) when it forms an ion.

Step3: Balance charges for compound

To balance the charges in an ionic compound, we need two $Li^+$ ions for every one $O^{2 -}$ ion. So the formula of the compound is $Li_2O$.

Step4: Identify bond type

Lithium is a metal and oxygen is a non - metal. When a metal and a non - metal react, they form an ionic bond.

Answer:

C. $Li_2O$, E. ionic
