### covalency

Specifies the degree of covalent character of a bond. A fully ionic bond might have covalency equal to 0.0, while a fully covalent bond might have covalency equal to 1.0.

    Example: <bond ... covalency="0.5"/> (no default)
    Allowed values: positive real (optional)

### order

Specifies the bond order, 1.0 for a single bond, 2.0 for a double bond, 3.0 for a triple bond and 1.5 for a benzene aromatic bond.

In wired mode, single, double and triple bonds are described by one, two and three paralel lines, respectively. In solid mode, a single bond is described by a cylinder, a double bond has two additional cylinders coming slightly outside of the central cylinder, opposite to each other, and a triple bond has two more additional cylinders, all four making angles of 90 degrees between them.

    Example: <bond ... order="1.0"/> (default)
    Allowed values: positive real (optional)
