Nodal surfaces in 2s and 3px orbitals, and evidence for octet stability

[amtmail]

Hello everyone.
here i come back again.
I have a homework question that i really need help with. the question says:
How many nodal surfaces are there for a 2s orbital and for a 3px orbital?

There is another question that says: What evidence indicates that the octet structures might be more stable than others?

I am wating for ur respose...please respond to me as soon as possible... i really need ur help.

First question has recently been asked and answered here, due a search. Second question is some how resonating with me ;)

We can not respond until you post your thoughts first...

ok i think i got it

for the first question...i think a 2s orbital has ero nodal surfaces and a 3px orbital has 3 or 1 nodal surfaces...i am not really sure

for the second question is it when the atom doesn't react with any other atom because it is stable.?? for ex. noble gases??

For your first question, this website should give you straightforward visual answers:http://www.shef.ac.uk/chemistry/orbitron/AOs/3s/index.html

Very good. Chemical inertness is definitely evidence of the stability that comes from the octet configuration.

please inform me.

Thanx for answering my second question. I was wondering if u could tell me if my answer to the 1st question was right. please tell me if it is right or wrong because i am not sure abt it..
