Question #bcd5b

Answer 1

`K_2O`

Explanation:

Potassium has a tendency to lose `1` electron to become `K^+`, while oxygen wants to gain `2e^-` to complete its octet, so it becomes `O^(2-)`.

Combining,

`K^+` `O^(2-)`

We have to criss cross, so the `2` goes to potassium, while `1` goes to oxygen, so our final formula is:

`K_2O`

This is a compound called potassium oxide.
