How are lighter elements formed
WebThe reaction is therefore a fusion of two carbon-12 nuclei, and no other particles are produced: 12 6 C + 126 C → 2412Mg. The neon-20 product has Z = 10 and A = 20. The conservation of mass requires that the other product have A = (2 × 12) − 20 = 4; because of conservation of charge, it must have Z = (2 × 6) − 10 = 2.

During the formation of the universe some 14 billion years ago in the so-called ‘Big Bang’, only the lightest elements were formed – hydrogen and helium along with trace amounts of lithium and beryllium. As the cloud of cosmic dust and gasesfrom the Big Bang cooled, stars formed, and these then grouped … Ver mais For most of their lives, stars fuse elemental hydrogen into helium in their cores. Two atoms of hydrogen are combined in a series … Ver mais When a star’s core runs out of hydrogen, the star begins to die out. The dying star expands into a red giant, and this now begins to manufacture carbonatoms by fusing helium atoms. More massive stars begin a further series … Ver mais Only 90 of the 116 known elements occur naturally, so where have the other 26 come from?

For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together.
