WebWe find that at low potentials (<0.5 V) Cu/WC and Pd/WC core–shell particles catalyze CO2 reduction to CO as the main product due to low COOH formation and CO desorption free energies. Furthermore, we show that the binding energies of the carbo- and oxo-intermediates on the M/WC catalyst surface obey scaling relations with the binding … WebK is the name of the first orbit, L is the second, M is the third, and N is the name of the fourth orbit. The electron holding capacity of each orbit is 2n 2. Electron holding capacity of shells For example, n = 1 for K orbit. The maximum electron holding capacity in K orbit is 2n 2 = 2 × 1 2 = 2. For L orbit, n = 2.
