Sagot :
Answer:
The correct answer is (4) number of valence electrons
Explanation:
Lithium (Li) and potassiun (K) belong to the group 1A of the Periodic Table and are called Alkali Metals. The elements of this group have only one electron in their highest energy orbital (ns¹), so they have the same number of valence electrons. Notice that Li has 1 electron in its higher energy orbital of 2nd level (2s¹) and K has 1 electron in its highest energy orbital of 4th level (4s¹).
