Verified step by step guidance1
Recall that the atomic number of an element is defined as the number of protons in its nucleus.
Identify the atomic numbers of the given elements: Titanium (Ti), Manganese (Mn), Chromium (Cr), and Vanadium (V).
Use the periodic table to find the atomic number for each element: Titanium has atomic number 22, Manganese has 25, Chromium has 24, and Vanadium has 23.
Compare these atomic numbers to the given number 23 to determine which element matches.
Conclude that the element with 23 protons (atomic number 23) is Vanadium (V).
