Well, given the element, you take a gander at the Periodic Table......

Explanation:

No-one is expected to memorize the Periodic Table at the undergraduate level. The Periodic Table lists #Z#, #"atomic number"#, and average isotopic mass for all the 100 or so known elements. A copy of the Periodic Table will be made available in every Chemistry/Fysics exam you sit as an undergrad or 6th form student.
