With what element does hydrogen combine to make water?
Hide Answer
Answer:
Oxygen
Explanation:
Hydrogen combines with oxygen to make water because oxygen has a higher electronegativity than hydrogen, leading to the formation of polar covalent bonds between the two elements. This allows for the sharing of electrons, resulting in the creation of water molecules where oxygen attracts more electrons, giving it a partial negative charge, while hydrogen becomes partially positive. This polarity gives water its unique properties such as cohesion, adhesion, and surface tension.
