In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water, each hydrogen atom is indeed heavier, with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D20.

Bonds. Add bonds. Add a bond type to a single atom: Select a bond type (see below), point to the atom on the canvas, and then drag outwards from the atom. Add a bond between two atoms: Select a bond type (see below), point to an atom on the canvas, and then drag the pointer to another atom.
Zoom in on structures on the canvas. Choose the Zoom in or Zoom all (for maximum size) from the top toolbar. Scroll bars become active if the structure is larger than the canvas.
