What are the 5 most important elements?
1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What are the 5 most abundant elements in the universe?
- 1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, ~70% of the Universe remains hydrogen.
- 2.) Helium. About 28% is helium, with 25% formed in the Big Bang and 3% from stellar fusion.
- 3.) Oxygen.
- 4.) Carbon.
- 5.) Neon.
- 6.) Nitrogen.
- 7.) Magnesium.
- 8.) Silicon.
How rare is gold in the universe?
Gold is rare throughout the Universe because it’s a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the ‘chemical forges’ of supernovae, the deaths of giant stars responsible for creating most chemical elements.
