How were the heavier elements formed
Web9 apr. 2024 · The scarcity of heavier elements made it harder for the gas in the stellar nurseries to cool down and condense, resulting in a higher threshold of gas needed to collapse and form stars. As a result, the first generation of stars were massive and hot, evolving rapidly and exploding as supernovae, scattering some of the heavier elements … WebElements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Atomic number The number of protons in an atom. Electron configuration
