What is the electron configuration of Ti2+?

Verified step by step guidance

1. Step 1: Identify the atomic number of titanium (Ti), which is 22. This means a neutral titanium atom has 22 electrons.
2. Step 2: Write the electron configuration for a neutral titanium atom. The configuration is: \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2\).
3. Step 3: Recognize that \(Ti^{2+}\) means the titanium atom has lost 2 electrons.
4. Step 4: Remove electrons starting from the outermost shell. Electrons are removed from the 4s orbital first, followed by the 3d orbital if necessary.
5. Step 5: Adjust the electron configuration by removing 2 electrons from the 4s orbital: \(1s^2 2s^2 2p^6 3s^2 3p^6 3d^2\).
