Give the electron configurations of
22Ti+2
Do you know how to do this? Here is a site that will help you. Repost with specific questions about the points you don't understand. http://www.iun.edu/~cpanhd/C101webnotes/modern-atomic-theory/aufbau-principle.html
To determine the electron configuration of an ion, such as Ti+2 (titanium ion with a +2 charge), we first need to know the electron configuration of the neutral atom of titanium.
The atomic number of titanium (Ti) is 22, which indicates that it has 22 electrons in its neutral state. The electron configuration of a neutral titanium atom can be represented as 1s2 2s2 2p6 3s2 3p6 4s2 3d2.
When a titanium atom loses two electrons to form Ti+2, we remove the two outermost electrons from the 4s orbital. Therefore, the electron configuration of Ti+2 can be written as 1s2 2s2 2p6 3s2 3p6 3d2.
If you need further clarification or have specific questions about any aspect of the electron configuration, please let me know.
