            {
                "atomicNumber": 1,
                "name": "Hydrogen",
                "atomicWeight": 1.00794,
                "phase": "Gas",
                "ionization": 13.5984,
                "melting": -259.15,
                "boiling": -252.87
            },
            {
                "atomicNumber": 2,
                "name": "Helium",
