Popular questions
How many valence electrons does nitrogen have?
Five; a nitrogen atom has 5 valence electrons (2s2 2p3).
What is nitrogen fixation?
Nitrogen fixation is the conversion of atmospheric N2 (E941) into biologically available forms like ammonia by microbes, lightning, or the industrial Haber–Bosch process.
What is nitrogen used for?
In foods, E941 is used as an inert propellant and packaging gas to displace oxygen, prevent oxidation, and extend shelf life. Liquid nitrogen is also used for rapid freezing and to create fine bubbles/creamy textures in beverages (e.g., nitro coffee or beer).
Is nitrogen a greenhouse gas?
No—diatomic nitrogen (N2, E941) is not a greenhouse gas because it does not absorb infrared radiation; nitrous oxide (N2O, E942) is.
What is the nitrogen cycle?
The nitrogen cycle is the movement of nitrogen among the atmosphere, soils, water, and living organisms. It includes fixation of N2 (E941) into reactive forms, biological uptake, and return to N2 via processes like denitrification.
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.
