()`getElement`-
Returns the
`element`

object for an atom.

([`coordinates``x, y, z`])-
Sets or returns the Cartesian coordinates for an atom. If
`x`,`y`, and`z`are given as doubles the Cartesian coordinates are set to`x`,`y`, and`z`. Otherwise a tupel with the x, y, and z coordinates and the name of an atom is returned.

([`radius``rad`])-
Sets or returns the Van der Waals radius for an atom. If
`rad`is given it has to be a double. The Van der Waals radius is measured in Ångstrøms.

([`radiusScaleFactor``scaleFactor`])-
Sets or returns the scale factor for the radius of an atom. If
`scaleFactor`is given it has to be a double. The scale factor must be greater than or equal zero.

([`neutronScatteringFactor``factor`])-
Sets or returns the neutron scattering factor for an atom. If
`factor`is given it has to be a double. The neutron scattering factor must be greater than or equal zero.

([`name``name`])-
Sets or returns the name of an atom. If
`name`is given it has to be a string. The maximum length of the string is eight characters.

(`replace``elementSymbol`)-
Replaces the atom with an atom of element
`elementSymbol`.`elementSymbol`has to be a string and a valid element symbol.

()`delete`-
Deletes this atom. Note: Atoms cannot be deleted using Python's
`del`

operator since Python works on VIEWMOL's data structures.
