Verified step by step guidance1
Recall that in a neutral atom, the number of electrons equals the number of protons, which is the atomic number of the element.
Identify the atomic numbers of the given elements: Manganese (Mn), Titanium (Ti), Vanadium (V), and Chromium (Cr).
Compare the atomic numbers to find which element has 23 protons, and therefore 23 electrons in its neutral state.
Use the periodic table to find: Titanium (Ti) has atomic number 22, Vanadium (V) has atomic number 23, Chromium (Cr) has atomic number 24, and Manganese (Mn) has atomic number 25.
Conclude that the element with 23 electrons in a neutral atom is the one with atomic number 23, which is Vanadium (V).
