Best ResponseYou've already chosen the best response.0n = the shell l (total nodes) = subshell which is 0...n1 in which so s = 0 p = 2 d= 3... radial nodes are nl1

Best ResponseYou've already chosen the best response.0what do u mean? im studying this right now too... ill give an example? lets say u have k which is potassium...1s2 2s2 2p6 3s2 3p6 4s1 the prinicple quantum number would be 4 because its form the 4th shell. the subshell would be n1 radial nodes is nL1

Best ResponseYou've already chosen the best response.0i know this one , what am asking is for the simple defenition of all 4 quantum nos , the principal , azimuthal , spin and magnetic quantum no's and their characteristic , i have a theory test that's y :

Best ResponseYou've already chosen the best response.1so for telling the orientation of a particular orbit...we need a 3rd quantum no...that is magnetic quantum no eg px, py, pz l=1 for p so m = l to +l m=1,0,+1 this corresponds to px, py and pz

Best ResponseYou've already chosen the best response.1similarly l=2 for d subshell, so m=2 to +2 m=2,1,0,+1,+2 so d orbital has 5 orientation

Best ResponseYou've already chosen the best response.1now the last onespin quantum no u know that each of px, py and pz contain 2 electrons

Best ResponseYou've already chosen the best response.1so for distinguishing between the two electrons in an orbital (px, py or pz) , we need a fourth quantum number.

Best ResponseYou've already chosen the best response.1u can understand it by assume that electron is spinning clockwise or anticlockwise. so s= either+1/2 or 1/2

Best ResponseYou've already chosen the best response.0okay , how do i use it , like how do they ask question regarding spin quantum no ?

Best ResponseYou've already chosen the best response.1u will be asked...write all the quantum nos of an electron in any atom..
