Which one of the following constitutes a group of the isoelectronic species ?A. `C_2^(2-), O_2^(-), CO, NO`B. `N_2, O_2^(-), NO^(+), CO`C. `CN^(-), N_2, O_2^(2-), C_2^(2-)`D. `NO^(+), C_2^(2-), CN^(-), N_2` |
|
Answer» Correct Answer - D Isoelectronic species have the same electronic configuration due to the same number of electrons. `C_2^(2-)=6+6+2=14, O_2^(-)=8+8+1=17` `CO=6+8=14, NO=7+8=15, N_2=7+7=14` `NO^(+)=7+8-1=14, CN^(-)=6+7+1=14` |
