Question

An orbital-filling diagram shows the number of electrons m each orbital, which are shown in order of energy. The placement of electrons in orbitals follows a certain set of rules. Lower energy subshells fill before higher energy subshells. The order of filling is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p. The periodic table can be used to help you remember this order. An orbital can hold up to two electrons, which must have opposite spins. Hund's rule states that if two or more orbitals with the same energy are available, one electron goes in each until all are half fun. The electrons in the half-filled orbitals all have the same value of their spin quantum number. How many orbitals are there in the third shell (n = 3)? Express your answer numerically as an integer. Show the orbital-filling diagram for N (nitrogen). Stack the subshells in order of energy, with the lowest-energy subshell at the bottom and the highest-energy subshell at the top. Use the buttons at the top of the tool to add orbitals. Click within the orbital to add electrons. Show the orbital-filling diagram for S (sulfur). Stack the subshells in order of energy, with the lowest-energy subshell at the bottom and the highest-energy subshell at the top. Use the buttons at the top of the tool to add orbitals. Click within the orbital to add electrons. Show the orbital-filling diagram for Br (bromine). Stack the subshells in order of energy, with the lowest-energy subshell at the bottom and the highest-energy subshell at the top. Use the buttons at the top of the tool to add orbitals. Click within the orbital to add electrons.
