atomic orbitals...nodal plane, nodal surface

1) 首先,atomic orbitals就係話你知electron唔再係一粒圍著atom轉既野.而係一個好隨意,冇辦法知道軌跡既wave. 因為係atomic level觀察,傳統既牛頓力學(newtonian mechanics)已經解釋唔到...

2) 而electron可以睇成係wave (因為佢有wavelength,&有齊wave既特性eg. reflection,diffration,interference.....)但係佢又有particle既特性(wave particle duality),即係話electron可以看成粒子or wave

3) 而冇辦法知道electron係邊既時候我地唯有用probability去解釋electron多數會係某邊個空間(至於點解可以咁.你要睇下一d講quantum chemistry - de broglie standing wave既book)

4) electrons看成粒子時,佢可以自轉(electron spin). 咁佢就有兩種轉法.可看成 + spin & - spin

5) 當一粒electron飛左去另一個orbital(same energy), electron就會轉spin.(由+ 去 - 或者到轉) 係o個個位就係nodal plane/nodal surface. 係zero probability搵到electron.因為electron唔會唔轉,唔會有spin state = 0. 咁講發係o個個位係唔會有electron (睇下一個叫particle in box theory)
