Question

5.) there is no number after the \o\ in li₂o because.... (1 point) ○ the formula is written incorrectly in the question ○ \o\ means \zero\ ○ there is only one oxygen atom

Explanation:

In chemical formulas, a subscript of 1 is not written. So in \( \text{Li}_2\text{O} \), the absence of a number after O means there is 1 oxygen atom. The first option is wrong as \( \text{Li}_2\text{O} \) is correct. The second option is wrong as O is the symbol for oxygen, not related to zero.

Answer:

C. There is only one oxygen atom
