Question
Use the electron configurations of $\mathrm { H }$ and $\mathrm { O }$ to explain why these atoms combine chemically in a two-to-one ratio to form water.
Step 1
This means that hydrogen has one electron in its 1s orbital. However, the 1s orbital can hold up to two electrons. Therefore, hydrogen is looking to gain one more electron to fill its 1s orbital. Show more…
