Popular questions
What element has 18 electrons?
Argon (E938); a neutral argon atom has 18 electrons because its atomic number is 18.
What element has 18 neutrons?
The argon isotope argon‑36 (36Ar) has 18 neutrons (36 − 18 = 18).
What element has 18 protons?
Argon—its atomic number is 18, meaning it has 18 protons.
What element has 17 protons and 18 neutrons?
Chlorine‑35; that nucleus (17 protons, 18 neutrons) belongs to chlorine, not argon.
Which element has 18 electrons?
Argon (E938); a neutral argon atom carries 18 electrons.
What is nitrous oxide used for?
In foods, E942 is used as a propellant and foaming gas for aerosol whipped cream and similar products, and it helps limit oxidation by displacing oxygen; outside food, it’s also used medically for sedation and analgesia.
Why don't dentists use nitrous oxide anymore?
Many dentists still use it; where it’s reduced or discontinued, it’s usually due to practice policies, monitoring and ventilation requirements, costs, or infection-control considerations, not because it’s been broadly banned.
How does nitrous oxide work?
As a food additive, it dissolves in cream under pressure and expands into fine bubbles when released, whipping and dispensing the product while displacing oxygen to slow oxidation.
How long does nitrous oxide last?
In medical/dental use, its effects generally wear off within a few minutes after inhalation stops; in whipped cream, the gas remains in the foam for hours but gradually diffuses out.
Is nitrous oxide flammable?
No—nitrous oxide isn’t flammable, but it is a strong oxidizer that can make other materials burn faster and more intensely.
