Interpret and use symbols for atoms, e.g. ( ^{12}_{6}C ), and ions, e.g. ( ^{35}_{17}Cl^{-} )

Describe the structure of the atom as a central nucleus containing neutrons and protons surrounded by electrons in shells

State that hydrochloric acid is a strong acid, as shown by the symbol equation, ( HCl(aq) ightarrow H^+(aq) + Cl^-(aq) )
