Clicker: which of the following phs is the most alkaline? ph 2, ph 12, ph 7, ph 8. Clicker: macromolecules of life: carbohydrates, lipids, nucleic acids, proteins. To understand the special mature of life, we first must understand the chemical and physical behavior of chemicals that make up living things. Anything that has mass and occupies space. Cannot be broken down to a simpler form. Periodic table of elements lists all known elements. Atoms smallest functional unit that retains the properties of an elements. Each element consists of one type of atom. Electron: negative charge; participates in chemical reactions; outer-shell electrons determine chemical behavior. Of the 92 natural occurring elements, twenty-five are essential to life. Four of these make up about 96% of the weight of the human body:
