Hey anurag !

First of all , u dont hav to call me "Bhaiya " !!!

And secondly , I remember u very well . What u r saying is right , but standard electrode potential of Li for the reaction - Li gives Li+ is 3.05 , the highest among all the elements . So , acc. to this , Li can form cation very easily and hence is most electropositive . I consulted many books but couldn't find S.E.P. value of cesium . So , thats why I am getting confused among Li and Cs . !!! And yes , Fr should be most electropositive , but since it is radioactive , hence it is not considered !!!!

Now about ur problem , I am rating you for ur answer to that atomic orbitals question . But tell me is 27 the correct answer ?????

And , I hope we are friends now and will help answering each others good questions !!!

I'll be waiting for ur reply !!!!!!

Hi kgh !

well thnks for your explanation . It cleared my doubts to some extent . And I hav seen ur reply for rainbow que . Thanks for that too !!!!!!!

Hi gautam !

well, thanks for the suggestion , but I dont have the book , so I'll borrow it from someone and try to see if it can help me . Would u mind telling me something about coriolis forces . I'll be waiting for ur reply !

Thanks !!!!!

Hi kghedriu !

So , should i call u gautam or harsha ?

Anyways , what r u preparing for ????

I believe u r an south Indian ?

am i right ???

Hey vasanth !

In which class r u presently studying ?What are u preparing for ?

I think we can be friends and help each other in our preparations !Well , I am preparing for IITJEE2008 and am presently giving my Final exams for class XI.

Can we be friends ???????

So , is it basically a pseudo force ???

And what are its uses in circular motion ???? 

Hi vasanth !

Here's what I feel ,

Cs should be more electropositive bcoz it has lowest I. E . But , if we look at standard electrode potentials , then Li is most electropositive !!!

Pls help !!!!!!!!!

Good explanation kghedriu . U deserve a salute !

By the way , whats ur name ???

Hi anshuman !

yes , ur explanation is right for both que 1 and 2 , but for que -2 , I hav my own explanation , Can we answer this problem by inertia ???

Also , this que is from the ch - circular motion . So , I need a ans. using those concepls .

I agree with ans 1 , but I am not able to understand ans 2 . If friction would be large , then it would be easier to walk on ice !

Pls explain !!!!!

Is there any expert who can provide me with the solution of this question ?????

I would be very thankful !

Pizza's , because I like them . What about books ?

HC Verma or Arihant ????

Hey vasanth !

How can u say that a rainbow is a 'circular ring of colours' . Why cant it be of any other shape ?????

U must hav read about the formation of rainbow by dispersion of light from tiny droplets acting as prisms . But this does not explain its shape ????

Think about it !

What are coriolis forces ?

I read about them in HC Verma .Pls post useful and relevant information .
