yes, electrons are always moving in any orbit
so in when we have a electronegative atom and non electronegative atom how are the elctrons behaving in the bond
They 'hybridize' their orbitals, which is a pretty complex thing to understand exactly. Basically the geometry of orbitals of the atomic structure mixes with the geometry of the other element. This makes a new kind of orbital geometry called a hybrid orbital.
okay so if we have fo example oxygen bonded to a hydrogen . the oxygen we pulls the elctrons in the bond towards itself
Yes, the orbital geometry will reflect that. So the electrons spend more of their time on the oxygen side, but continue moving between the atoms.
so the electrons move back and forth in the hybrid orbitals. so at some point it may spend time on they hydrogen side and then move back to the oxygen side
when do we form hybrid orbitals?
Whenever two element combine chemically, even ionically, their orbital shape is distorted. So pretty much whenever a bond is formed as far as I know. -I'm looking for some notes I saw once on OCW
okay thank you . they hybrid orbitals allow the electrons to move back and forth
in the bond
here's what I was looking for: http://ocw.mit.edu/courses/materials-science-and-engineering/3-091sc-introduction-to-solid-state-chemistry-fall-2010/syllabus/MIT3_091SCF09_aln02.pdf also reference http://en.wikipedia.org/wiki/Orbital_hybridisation welcome!
hey nath,they actually vibrate.....not that sort of movement u ar visualizing in ur mind....
Not sure what you mean by 'vibrate'. They have a wave-like aspect and a particle-like aspect. Some bonds oscillate, but not all.
