The central Sn atom is bonded to the three Cl atoms and has one nonbonding pair on it. Therefore, the Sn atom has four electron domains around it. The resulting electron-domain geometry is tetrahedral (Table 9.1) with three of the corners occupied by the bonding pairs of electrons.
Glad to help you :)

Electron affinity is the change in energy of an atom with a neutral charge when an electron is added to form an anion. A more negative electron affinity corresponds to a greater attraction for an electron. Electron affinity become less negative down a group and from left to right in the periodic table.
