What are the shapes and designations of the f orbitals? The exotic‚ complex f orbital shapes are rarely shown in textbooks. General (and organic) chemistry traditionally focuses on the lighter elements‚ but the forbitals aren’t occupied in the ground state until element 58 (cerium). Even for elements beyond cerium‚ the f orbitals are deeply buried beneath the valence shell and they rarely play an important role in chemical change or bonding. However‚ the orbital shapes can be useful in interpreting

The purpose of this essay is to research and evaluate the digestive system effectively and extensively. Then describe the differences and indifferences of three different organisms in relation to their digestive system. The three organisms that have been chosen are the human‚ for comparative purposes‚ the Goliath Bird Eating Spider and the Cobra Lily carnivorous plant. The Human Digestive System Digestion is the breaking down of substance in the body‚ into an easier form of which it can be absorbed
