What ratio of hydrogen to oxygen atoms is found in a water molecule?

In a water molecule (H₂O), the molecular formula indicates that there are two hydrogen atoms for every one oxygen atom. This results in a ratio of hydrogen to oxygen of 2:1. This ratio is fundamental to understanding the composition of water and reflects the way the elements combine to form this essential substance. The specific bonding creates a stable arrangement where each oxygen atom bonds with two hydrogen atoms, leading to the properties of water that are crucial for life and various scientific processes.
