O 3. By comparing the Bohr Models and ionization energies, explain why Potassium (K) is more
reactive than Lithium (LI) and Sodium (Na)?

alkali metals:  hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).  These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.  The name comes from the fact that when these metals or their oxides are dissolved in water

ugh fiel iente of insistí is did kiwis jaj

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
