In The Entire Universe Which Is The Most Abundant Element. (ii) big bang nucleosynthesis makes very precise predictions (to $<1$ % precision) about the fraction of baryons that end up as protons vs other nuclei. Together they compose 99% of the visible universe.
In the universe as a whole, the most common element is hydrogen (about 90% of atoms), followed by helium (most of the remaining 10%). All other elements are present in relatively minuscule amounts, as far as we can detect. Hydrogen is the most abundant because it is the simplest element.
In The Universe As A Whole, The Most Common Element Is Hydrogen (About 90% Of Atoms), Followed By Helium (Most Of The Remaining 10%).
Web the most abundant element in the universe. Web hydrogen is the most abundant element in the universe and helium is second. Though we feel that oxygen occurs in abundance but if we talk about the most element in the universe, then the answer is hydrogen.
All The Other Elements Together Only Account For A Bit More.
The universe the universe includes. Then, the core of helium contracts, supplying enough pressure to fuse two helium nuclei into carbon. In stars, hydrogen fuses into helium.
The Other Elements Are Mostly Made By Nuclear Fusion In Stars, Especially Fusion During Supernova Explosions.
Web hydrogen — with just one proton and one electron (it's the only element without a neutron) — is the simplest element in the universe, which explains why it's also the most abundant, nyman said. The 3/4th of the entire universe comprises hydrogen or you can say that 70% of the universe is made up of hydrogen. Hydrogen is by far the most abundant.
Together They Compose 99% Of The Visible Universe.
Silicon is second, making up 28%, followed by aluminum (8%), iron (5%), magnesium (2%), calcium (4%), sodium (3%), and potassium (3%). Hydrogen is the most abundant because it is the simplest element. Helium makes up most of the remaining 25%.
All Of The Other Elements Are Relatively Rare.
Most of the hydrogen on earth exists in molecular forms such as water and organic compounds. Yet, it makes up about 22 percent of the universe. Web the three most abundant elements in the universe are the gasses:
