Transition metals

Noble gases are inert because

They have to lose one electron

They have to gain one electron

They already have a full outer shell of electrons

Helium is used in balloons because

it is inert

it has a low density

it is cheper than hydrogen

Neon is used in light bulbs because

it is inert

it has a low density

oxygen would react with the filament

Argon is used in welding

it is inert

it has a low density

it stops the metal racting with the oxygen in the air
