From New Latin helium, from Ancient Greek ἥλιος (hḗlios, “sun”) (because its presence wasFrom New Latin helium, from Ancient Greek ἥλιος (hḗlios, “sun”) (because its presence was first theorised in the Sun's atmosphere) with the suffix + -ium.

It is likely that Lockyer, being an astronomer, was unaware of the usual chemical conventions.
