Oxygen is chemically active because it reacts with other chemicals such as hydrogen to form water.
Argon is a chemically inactive non metal.
Helium has completely filled valence orbitals (and thus has stable electronic configuration). Hence is is chemically inert or inactive. In fact, helium doesn't react with any other element.
Helium, neon, argon are used because they are chemically inactive.
LSD may chemically break down and become inactive when exposed to light.
