Moving from the element with atomic number 10 to atomic number 11 on the periodic table, there is a change in reactivity. Which of the following are true? You MUST select ALL correct answers to earn full credit for this question.

reactivity increases
reactivity decreases
neon has another shell (energy level, orbit), meaning the atom will be larger
sodium has another shell (energy level, orbit), meaning the atom will be larger
valence electrons in sodium are farther from the nucleus
atomic number 11 does not have a full electron shell.
