WebCarbon has 4 valence electrons, and its electron configuration is 1s^2 2s^2 2p^2. Now, in order for carbon to bond appropriately 4 times you could promote an electron from the 2s orbital to the 2p orbital (thus giving you 2s^1 and 2p^3). However, these orbitals still exist at different energy levels, and thus we use hybridization. WebYou multiply the number of molecules times how many of that atom are present in the molecule. Sometimes, you will be asked for the total atoms present in the sample. (6.02 x 1023molecules) (3 atoms/molecule) = 1.81 x 1024atoms (to three sig figs) The 3 represents the total atoms in one molecule of water: one O atom and two H atoms. cincinnati bengals home game tickets
