How elements are formed — Science Learning Hub
Four atoms of hydrogen are combined in a serie s of steps to create helium-4. These reactions account for 85% of the Sun’s energy. The remaining 15% comes from reactions that produce the elements beryllium and lithium.
Physics - The Sounds of Atoms
2023年1月9日 · From top to bottom, the left column shows hydrogen, helium, lithium, beryllium; the middle column shows boron, carbon, nitrogen, oxygen; and the right column shows fluorine, neon, sodium, magnesium. The sound of each atom can be heard here.
Nucleosynthesis – How Elements Are Made - Science Notes and ...
2022年6月22日 · Big Bang nucleosynthesis: The Big Bang produces most of the protium (hydrogen-1), deuterium (hydrogen-2), helium-3, and helium-4 found in the universe today. A small amount of lithium-7 and beryllium-7 formed in the first 100 to 300 seconds after the Big Bang. Possibly, some boron formed.
First 20 Elements of Periodic Table - Name and Symbols
2024年3月18日 · The first ten elements in the periodic table are as follows: Hydrogen (H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne). Let us discuss each of these in detail one by one.
This Is Why Three Of The Lightest Elements Are So ... - Forbes
2019年11月14日 · If you were to add hydrogen to helium, you'd create lithium-5, which is unstable and decays almost immediately. You could try to fuse two helium-4 nuclei together to make beryllium-8, which...
16.1: The Formation of the Lightest Elements - Physics LibreTexts
Some of the most intriguing celestial observations are of the lightest elements: hydrogen (H), helium (He), lithium (Li), and the isotope of hydrogen known as deuterium (2 H; 1 proton and 1 neutron, often denoted D).
Composition of the Universe – Element Abundance
2022年6月28日 · As the universe ages, hydrogen fuses into helium. Eventually, helium becomes more abundant than hydrogen. One explanation for the low abundance of beryllium is that it has only one stable isotope, so it changes into other elements via radioactive decay.
