which of the following is the correct electron configuration for titanium (ti)?\n1s²2s²2p⁶3s²3p⁶4s²3d²\n1s²2s…

Explanation:

Step1: Recall atomic number of Ti

Titanium has atomic number 22, so it has 22 electrons.

Step2: Fill orbitals according to Aufbau principle

Electrons fill orbitals in order of increasing energy: 1s (2 electrons), 2s (2 electrons), 2p (6 electrons), 3s (2 electrons), 3p (6 electrons), 4s (2 electrons), 3d (remaining electrons). 1s²2s²2p⁶3s²3p⁶ accounts for 2 + 2+6 + 2+6 = 18 electrons. Remaining 22 - 18 = 4 electrons go first to 4s (2 electrons) and then 3d (2 electrons), giving 1s²2s²2p⁶3s²3p⁶4s²3d².

Answer:

1s²2s²2p⁶3s²3p⁶4s²3d²
