6. What pattern did you notice in valence electron configuration as you moved through
elements 3–18?

Answer:
The maximum number of valence electrons is 8
Explanation:
element 3 has 3 valence electrons. 7 has 5, and 10 has 8, as we increased the number of electrons in element 11, the number of valence electrons became 3, and the pattern went on, it cannot exceed 8.
