Question

q. 16. what is the correct electron - configuration for titanium? 1s² 2s² 2p⁶ 3s² 3p⁶ 3d² 4s² or ar 3d² 4s² 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d² or ar 4s² 3d² 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d³ or ar 4s¹ 3d³ 1s² 2s² 2p⁶ 3s² 3p⁶ 3d³ 4s¹ or ar 3d³ 4s¹

Explanation:

Titanium has an atomic number of 22. The electron - filling order follows the Aufbau principle, Pauli exclusion principle, and Hund's rule. The correct electron configuration is 1s²2s²2p⁶3s²3p⁶4s²3d² or [Ar]4s²3d².

Answer:

1s²2s²2p⁶3s²3p⁶4s²3d² or [Ar]4s²3d²
