Verified step by step guidance1
Understand that the oxidation state of an element is the charge it would have if all bonds were ionic. Transition metals can have multiple oxidation states.
Recognize that the highest oxidation state for a transition metal is often related to the number of valence electrons it can lose. For first-row transition metals, this is typically the sum of the electrons in the 3d and 4s orbitals.
List the first-row transition metals and their electron configurations: Sc (3d¹ 4s²), Ti (3d² 4s²), V (3d³ 4s²), Cr (3d⁵ 4s¹), Mn (3d⁵ 4s²).
Calculate the maximum oxidation state by counting the total number of electrons in the 3d and 4s orbitals that can be lost. For example, Cr can lose all 6 electrons (3d⁵ 4s¹) to achieve an oxidation state of +6.
Compare the calculated maximum oxidation states for each metal: Sc (+3), Ti (+4), V (+5), Cr (+6), Mn (+7). Identify that Cr has the highest possible oxidation state of +6 among the given options.
