These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). WebAllotropes of Carbon Definition: The molecular arrangement of the carbon atom is (2, 4), as shown by its atomic number of 6. The outermost shell of a carbon atom contains four electrons, so it shares them and enters the inactive gas state. The carbon atom forms covalent bonds with other atoms as a result. overlord x marvel fanfiction
