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
First, we need to determine the electron configurations of H and O atoms. Hydrogen (H) has 1 electron, so its electron configuration is 1sĀ¹. Oxygen (O) has 8 electrons, so its electron configuration is 1sĀ² 2sĀ² 2pā“. Show more…
