Hey guys please answer this, Question:1(i) What is the similarity in the electron configuration of lithium, potassium and sodium.(ii) Which element is the most reactive from above (i) and Why? |
| Answer» SIMILARITIES between Lithium , Sodium and Potassium is that all the 3 metals have 1 electron in their outermost orbital.(ii) From above Potassium is most reactive becauseLi - 1s²2s¹ - Is a stable electronic configuration since primary's' orbital is PARTIALLY filled.Na - 1s²2s²2p6 3s¹ - Outermost orbital is less stable due to less nuclear charge and more shielding energy.K - 1s²2s²2p6 3s²3p6 4s¹ - Even lesser nuclear charge and more shielding energy.THANK YOU FOR THE WONDERFUL QUESTION...#bebrainly | |
