oxygen – el oxigeno

(Pronounced ohk-see-heh-noh)

To remember that oxygen is pronounced ohk-see-heh-noh (oxigeno) in Spanish, use the following mnemonic:

Using oxygen tanks, the ox goes deep-sea diving with a hare that knows (oxigeno) the way.

Oxigeno is masculine, so it's el oxigeno. Imagine an elephant using an oxygen tank.
