The metals found in Fischer-type and Schrock-type carbenes have low and high values for this quantity respectively. The 18-electron rule is applicable for low values of this quantity for metals in organometallic complexes. (-5[1])For a given pH, this quantity is found on the x-axis of Frost–Ebsworth diagrams. Relativistic effects (10[1])affecting the 6s orbital allows gold to assume a negative value of this quantity. (10[1])Due to the inert-pair effect, (-5[1])larger Group 14 elements tend to reduce the value of this quantity (10[1])by 2. (10[1])Fluorine (-5[1])is the only (-5[1])halogen (-5[1])to exclusively (-5[1])have a value of negative one for this quantity. (10[1]-5[2])For 10 points, name this quantity that gives the number of electrons (10[1])lost from an atom during bonding. ■END■ (10[7]0[1])
