We’re being asked to match the given name of elements with their symbols.

Recall the mnemonics used for diatomic molecules:

Have   No       Fear     Of       Ice      Cold    Beer
H2(g)    N2(g)    F2(g)    O2(g)    I2(s)      Cl2(g)   Br2(l)­

Refer to the periodic table for the classification and symbol for each element:
