以phosphorus為例
其實點解佢的hybridization要sp3d
即1個3s 3個3p 1個3d
點解唔可以sp3s
即1個3s 3個3p 1個4s
係咪hybridization就一定要same shell of electron
唔洗理佢地之間的energy差異嗎?
更新1:
PCl5 真係sp3d wor
更新2:
PCl5 真係sp3d wor 佢3s electron can be excited into 3d orbital thus 5個相等energy orbitals for 5 bonds
更新3:
在phosphorus黎講 由於佢係冇3d electron在ground state so 4s orbital 係照理lower energy than 3d orbital 但為左想form 5個bonding 就expand its low lying d orbital 成sp3d 5個orbital 但我最唔明係點解有得揀佢唔揀當時較少energy gap的4s and 3p 而要選3p and 3d 呢???
