Question

potassium metal or nonmetal

Answer 1

YOUR ANSWER....___⤵
WHAT ARE AKALI..METALS..
=》Low ionization energies to make +1 cations
=》M+ ions are spherical and hard (low polarizability)
=》 High 2nd ionization energies prevent the +2 oxidation state
=》Most bonding interactions are ionic due to low polarizability (Li+ is strongest in terms of Lpolarizing ability due to size/charge ratio – in other words it forms the most covalent compounds)
=》Li is least reactive, Cs is most reactive

《AND THATS WHY THE POTASSIUM IS #ALKALI# TYPE OF METAL》
