What is the 3rd most abundant element?
What is the 3rd most abundant element?
Oxygen
Oxygen is the third most abundant element in the Universe today, and in the very, very far future, may even have the opportunity to rise further as hydrogen (and then possibly helium) falls from its perch.
What are 3 abundant elements in outer space?
- 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.
What are the three abundant elements?
The mass-abundance of the nine most abundant elements in the Earth’s crust is approximately: oxygen 46%, silicon 28%, aluminum 8.3%, iron 5.6%, calcium 4.2%, sodium 2.5%, magnesium 2.4%, potassium 2.0%, and titanium 0.61%. Other elements occur at less than 0.15%.
What is the 3rd most abundant element in the sun?
Composition of the Sun
| Element | Abundance (percentage of total number of atoms) | Abundance (percentage of total mass) |
|---|---|---|
| Hydrogen | 91.2 | 71.0 |
| Helium | 8.7 | 27.1 |
| Oxygen | 0.078 | 0.97 |
| Carbon | 0.043 | 0.40 |
What is the most plentiful element in the universe?
Hydrogen
Hydrogen and Helium. Hydrogen is an element, usually in the form of a gas, that consists of one proton and one electron. Hydrogen is the most abundant element in the universe, accounting for about 75 percent of its normal matter, and was created in the Big Bang.
What is the strangest element?
The most weird and wonderful elements in the periodic table
- Krypton (Atomic number: 36)
- Curium (Atomic number: 96)
- Antimony (Atomic number: 51)
- Copernicium (Atomic number: 112)
- Bismuth (Atomic number: 83)
Why is hydrogen so special?
Hydrogen is special among the elements for the reason it can easily form compounds in either the +1 or -1 oxidation states, where it can act essentially like a metal or a non-metal, depending on the circumstances. This fact is what allows hydrogen to be present in so many different compounds.
Why is oxygen the 3rd most common element?
The explanation is needed, because there are more stars (and more total mass in stars) that burn helium to carbon than there are stars massive enough to build oxygen.
What is the rarest item in the universe?
He designed a rocking horse made of 24-carat gold. Scientists have spotted the “rarest event ever recorded”, in a major breakthrough as part of attempts to solve a dark matter mystery.
