Answer :- Electrons are located around the nucleus in the Orbital !!
Orbital :-
It is the three dimensional space around the nucleus in an atom where the possibility of finding an electron is maximum ( Upto 90% )
( The position where the possibility of finding an electron is zero is called as Node !! )
- According to Schrodinger's wave equation , for an electron wave equation is [ file 2 ]
- File 1 is solution of S.W equation !
- The electron follows wave equation !!
- Also , according to Heisenberg's Uncertainty principle :-
"" Simultaneously and accurate measurement of position and velocity of an electron in an atom can't be determined ""
