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