Pure watter (H2O), seen in the tap image, is an example o a compoond: the baw-an-stick model o the molecule (above) shaws how watter consists o twa pairts hydrogen an ane pairt oxygen

A chemical compoond is a pure chemical substance consistin o twa or mair different chemical elements[1][2][3] that can be separatit intae simpler substances bi chemical reactions.[4] Chemical compoonds hae a unique an defined chemical structure; thay consist o a fixed ratio o atoms[3] that are held thegither in a defined spatial arrangement bi chemical bonds. Chemical compoonds can be molecular compoonds held thegither bi covalent bonds, sauts held thegither bi ionic bonds, intermetallic compoonds held thegither bi metallic bonds, or complexes held thegither bi coordinate covalent bonds. Pure chemical elements are nae considered chemical compoonds, even if they consist o molecules that contain anly multiple atoms o a single element (such as H2, S8, etc.),[5] which are cried diatomic molecules or polyatomic molecules.
