Valence electron of zinc atom possesses the quantum numbers n = 3, l = 2, m = +2 to -2 and s = + ½ or - ½.

• A. True
• B. False

The statement about the valence electron of a zinc atom is False.

Explanation of Zinc's Electron Configuration

Zinc (Zn) has an atomic number of 30, which means it has 30 electrons. The electron configuration for zinc is:

• 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²

Understanding Quantum Numbers

For the outermost electrons in zinc, the relevant quantum numbers are:

• n (principal quantum number): 4 (for the 4s electrons)
• l (azimuthal quantum number): 0 (for s orbital)
• m (magnetic quantum number): 0 (for s orbital)
• s (spin quantum number): +½ or -½

Thus, the valence electrons of zinc do not match the quantum numbers provided in the statement. The correct quantum numbers for zinc's valence electrons are different, confirming that the statement is indeed false.
