## Description

This is a data base associating symbol names and atomic numbers. One can also get the covalent radius of chemical species. It is convenient to plot bindings.

## Details

### toolElementsGet_element ()

    gboolean            toolElementsGet_element             (gchar **name,
                                                             float *radcov,
                                                             int zele);

Get the symbol or the covalence radius of the argument `zele`.

`name` : | a pointer on an unallocated string (can be NULL) ;
`radcov` : | a pointer on a float (can be NULL) ;
`zele` : | the atomic number.
Returns : | TRUE if zele is known in the atomic built-in list.

### toolElementsGet_elementFromSymbol ()

    gboolean            toolElementsGet_elementFromSymbol   (int *zele,
                                                             float *radcov,
                                                             gchar *symbol);

Get the the covalence radius or the atomic number of a given atomic `symbol`.

`zele` : | a pointer on an integer (can be NULL) ;
`radcov` : | a pointer on a float (can be NULL) ;
`symbol` : | the symbol of an atom.
Returns : | TRUE if `symbol` is known in the atomic built-in list.
