Why is delirium oxide called heavy water it has extra oxygen atoms it has hydrogen atoms are heavier than other others it has extra hydrogen atoms it's oxygen atoms are heavier than others

Delirium oxide is not a term in chemistry. It seems like you might be referring to heavy water, which has the chemical formula D₂O or deuterium oxide. Heavy water is so named because it contains a heavier isotope of hydrogen called deuterium. The nucleus of deuterium consists of one proton and one neutron, whereas the nucleus of regular hydrogen (called protium) contains just one proton.

The extra neutron in deuterium makes it approximately twice as heavy as protium, which is why heavy water is denser than regular water. However, heavy water does not contain extra oxygen atoms. It has the same number of oxygen atoms as normal water (H₂O), but the hydrogen atoms in heavy water are replaced with deuterium atoms, making it "heavy."

Heavy water is used in various scientific applications, such as nuclear reactors and nuclear magnetic resonance spectroscopy, due to its unique properties.
