Here's why:
* Chemical Bonding: Oxygen atoms have a strong tendency to attract electrons, making them highly electronegative. Hydrogen atoms, on the other hand, are less electronegative. This difference in electronegativity allows oxygen and hydrogen to form covalent bonds, where they share electrons.
* Water Formation: In water, one oxygen atom shares electrons with two hydrogen atoms, forming a stable molecule. This is the most common compound formed by oxygen and hydrogen.
It's important to note that oxygen and hydrogen can also form other compounds like hydrogen peroxide (H₂O₂), but water is the most prevalent and essential compound.
