Question

question 8 (1 point)
how does the energy of an electron change when the electron moves closer to the nucleus?
o a it increases
o b it decreases
o c it doubles
o d it stays the same

question 6 (1 point)
what is the shape of the 3p atomic orbital?
o a dumbbell
o b sphere
o c bar
o d two perpendicular dumbbells

question 7 (1 point)
what is the maximum number of d orbitals in a principal energy level?
o a 5
o b 3
o c 1
o d 2

Explanation:

• Question 8: Electrons closer to the nucleus have lower energy. As an electron moves closer to the nucleus, it moves to a lower - energy state.
• Question 6: The \(p\) atomic orbitals (including \(3p\)) have a dumbbell shape.
• Question 7: The number of \(d\) orbitals in a principal energy level is always \(5\).

Answer:

• Question 8: B. It decreases
• Question 6: A. dumbbell
• Question 7: A. 5
