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 a hydrogen bond?
A hydrogen bond is a weak electrostatic attraction between a hydrogen atom bound to an electronegative atom (like O, N, or F) and another electronegative atom; it’s unrelated to E949, which is hydrogen gas used mainly as a packaging/propellant additive.
Does hydrogen peroxide expire?
Yes—household hydrogen peroxide (not E949) slowly decomposes to water and oxygen; unopened it typically lasts up to about a year in a cool, dark place, but after opening it’s best used within 1–3 months.
Is hydrogen water good for you?
Hydrogen water is water infused with dissolved hydrogen gas (E949); it’s generally safe, but evidence for meaningful health benefits is limited and not conclusive.
Is hydrogen a metal?
No—hydrogen is a nonmetal under standard conditions; as E949 it’s the colorless, flammable gas used as a food-packaging/propellant additive.
Does hydrogen peroxide kill mold?
3% hydrogen peroxide can kill mold on hard, nonporous surfaces, but it’s less effective on porous materials like wood or drywall; use in a ventilated area and don’t mix it with bleach or vinegar.
