The Aufbau Principle describes the order of subshells in an atom in terms of energy. Higher numbered shells have higher energy. It is complicated by occasiona overlapping. The specific order of subshells using the Aufbau Principle can be found using the diagonal arrow diagram found in Chapter 8, and this is the same order found on the periodic table. What is the order of subshells in period 7? (there are 4) 7s a. 1s b. 2s С. 3s d. 4s е. 5s f. 6s g. 7s h. 1p i. 2p j. Зр k. 4p I. 5p m. 6p n. 7p o. 1d р. 2d q. 3d r. 4d s. 5d t. 6d u. 7d v. 1f w. 2f y. 3f z. 4f aa. 5f bb. 6f сс. 7f
