Attribute   Type            Description
=========== =============== ================================================
`number`    ``int``         The atomic number of the element
`symbol`    ``str``         The symbol used for the element
`name`      ``str``         The IUPAC name of the element
`mass`      ``float``       The mass of the element in kg/mol
`covRadius` ``float``       Covalent bond radius in Angstrom
`isotope`   ``int``         The isotope integer of the element
`chemkinName` ``str``       The chemkin compatible representation of the element
