Question

14. Account for the difference in the electron affinity between B (27 kJ/mole) and Be (<0). 15. a-Sn has the same diamond structure as C (diamond) Si and Ge. Calculate the bond Sn-Sn bond using the cubic unit cell of the Sn crystal structure (see graphic) and determine the covalent radius of the Sn atom (see lecture notes). Hint: Sn-Sn bond length is ½ the body diagonal of the cube. 6.45 Å

Step 1

The electron affinity is the energy change that occurs when an electron is added to a neutral atom to form a negative ion. In the case of B, the electron affinity is 27 kJ/mol, indicating that it has a tendency to gain an electron and form a negative ion. On the Show more…

14. Account for the difference in the electron affinity between B (27 kJ/mol) and Be (<0). 15. -Sn has the same diamond structure as C (diamond), Si, and Ge. Calculate the Sn-Sn bond using the cubic unit cell of the Sn crystal structure (see graphic) and determine the covalent radius of the Sn atom (see lecture notes). Hint: Sn-Sn bond length is equal to the body diagonal of the cube, which is 6.45 Å.
