Problem

What is the ground-state electron configuration of a neutral atom of titanium? Express your answer in condensed form, in order of increasing orbital energy.

Solution
Solution

Before we can write the electron configuration for titanium, we must first know how many electrons it has. Atomic number tells us how many electrons a neutral atom has. To get the atomic number we'll simply have to look this up in the periodic table.  

Remember that for a neutral atom, the atomic number is just equal to the number of electrons. This is because the atomic number is based on the number of protons it has. Remember that neutral means a charge of zero, so to have a zero charge, the positively charged particles (protons) must equal the negatively charged particle (electrons).
