Francium is a metal, specifically an alkali metal. It is a highly reactive element that is typically found in compounds rather than in its pure form due to its extreme reactivity. Francium is the least stable of the alkali metals due to its position at the bottom of the Periodic Table, and it readily loses its single valence electron to form a positive ion.
None of the above. Thiamin is a compound and the terms metal, nonmetal and metalloid apply to elements.
