WebJan 23, 2024 · Ethene is made up of four 1s 1 Hydrogen atoms and two 2s 2 2\(p_x\) 1 2\(p_y\) 2 carbon atoms. These carbon atoms already have four electrons, but they each want to get four more so that they have a full eight in the valence shell. Having eight valence electrons around carbon gives the atom itself the same electron configuration as neon, a ...
