Answer

Brief Explanations:

  • For Question 4: In atomic - orbital theory, s orbitals are spherical in shape.
  • For Question 5: p orbitals have a dumbbell - shape.
  • For Question 6: Calcium (Ca) with an atomic number of 20 has 20 electrons. Filling the orbitals according to the Aufbau principle (filling lower - energy orbitals first), the electron configuration is (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}).

Answer:

Question 4: A. s orbital Question 5: B. p orbital Question 6: C. (1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2})
