An orbital is the region around the nucleus where an electron is most likely to be found; 3px has n = 3, l = 1, and 4d(x2-y2) has n = 4, l = 2.
Definition of orbital: An atomic orbital is the three-dimensional region of space around the nucleus where the probability of finding an electron is maximum (typically taken as 90-95%). It represents a solution of the Schrodinger wave equation described by the three quantum numbers n, l and m.
Quantum numbers:
- The principal quantum number n is simply the shell number written before the orbital symbol. …
