orbital A 1d B 2d C 3d D 4d E 5d F 6d G More information is needed 12 What is the maximum number of electrons that can occupy this orbital Answer by using an integer e g 0 1 etc 13 Which of the following options has the energy of orbitals pictured below ranked correctly from lowest energy to highest energy E B B A C D A B C D A B D C B D A C B A C D A B C D E 14 In a multi electron system an orbital in a 4s subshell fills before an orbital in a 3d subshell despite a higher quantum number n Which of the following statements best explain this behavior A A 3d orbital experiences less shielding than a 4s orbital B The 3d subshell is able to hold more electrons than a 4s orbital which subsequently results in a lower energy C There are more nodes in a 3d orbital than a 4s orbital causing an increase in energy D A 4s orbital experiences more penetration than a 3d orbital E The number of possible orientations for the 3d orbitals are higher than 4s orbitals resulting in a higher energy 15 Which of the following best describes the noble gas electron configuration of the ground state of cobalt A Ar 4s24d7 B Ar 4s14d8 C Ar 4d9 D Ar 4s23d7 E Ar 4s13d8 16 Which of the following
