Interpret and use symbols for atoms, e.g. ¹²C₆, and ions, e.g. ³⁵ ₁₇Cl ^–

EXTENDED:

State that isotopes of the same element have the same chemical properties because they have the same number of electrons and therefore the same electronic configuration
Calculate the relative atomic mass of an element from the relative masses and abundances of its isotopes
