Explain the significance of three Quantum numbers in predicting the positions of an electron inan atom. |
|
Answer» In CHEMISTRY there are 4 quantum umbers n, l , m and s .they are used to show the position of an electron in an atom .the first one is n that is principal quantum NUMBER .This describes the electron shell, or energy LEVEL, of an electron.2. The second one is l which is azimuthal quantum number.The value of l ranges from 0 to n − 1, so the first p orbital (l = 1) appears in the second electron shell (n = 2), the first d orbital (l= 2) appears in the third shell (n = 3), and so on.l = 0, 1, 2,..., n − 13. The third one is magnetic quantum number which is represented by m.This describes the SPECIFIC orbital within that subshell, and yields the projection of the orbital angular momentum along a specified axis.4.And the fourth one is spin quantum number which is represented by S .The value of s is -1 or +1 . |
