Question

Which option correctly describes the pattern of valence electrons on the periodic table?(1 point)

1.The number of valence electrons increases from top to bottom.

2.The number of valence electrons increases from bottom to top.

3.The number of valence electrons increases from left to right.

4.The number of valence electrons increases from right to left.

Answer 1

Answer:

1. valence electrons and electronegativity

2. Both reactivity and electronegativity decrease down a group.

3. Electronegativity decreases down a group, and reactivity increases down a group.

4. The number of valence electrons increases from left to right.
