exam 2: periodicity & electron configuration/em spectrum\nmany properties of titanium are determined by the electron arrangement within the titanium atoms.\nwhich is the noble - gas notation of titanium?\nar 4s²3d²\nar 4s²4d²\nar 4s²4p²\nar 4s²3p²

Answer

Brief Explanations:

Titanium has an atomic number of 22. Argon (Ar) has an atomic number of 18. After filling the argon - core, we need to account for 4 more electrons. According to the Aufbau principle, the next electrons go into the 4s orbital (2 electrons) and then the 3d orbital (2 electrons).

Answer:

[Ar] 4s²3d²
