The correct statement regarding the trend in valence electrons for lithium (Li), sodium (Na), and potassium (K) is:
**All three elements have the same number of valence electrons.**
All of these elements are in Group 1 of the periodic table and each has 1 valence electron. Therefore, while they are different elements with varying atomic numbers, they share the same number of valence electrons.
**All three elements have the same number of valence electrons.**
All of these elements are in Group 1 of the periodic table and each has 1 valence electron. Therefore, while they are different elements with varying atomic numbers, they share the same number of valence electrons.
