If we did not take an IR spectra of our final compound, what other types of analysis could we use to determine whether the oxidation occurred

The metal is named first

Sorry i dont understand the question can you rephase it?

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
