Hivy watter (deuterium oxide (2
H
2O )) is a form o watter that conteens a lairger nor normal amoont o the hydrogen isotope deuterium (2
H or D, forby kent as hivy hydrogen), rather nor the common hydrogen-1 isotope (1
H or H, forby cried protium) that maks up maist o the hydrogen in normal watter.[3]
