2.1 Describe matter, chemical elements, and chemical compounds. 2.2 Use examples to illustrate how the structure of an element's atoms determines its proper-ties. 2.3 Identify and describe the types of strong and weak chemical bonds, and use examples to show how bonds affect molecular shape.
The Chemistry of Life unit explores the fundamental building blocks of living organisms, from atoms and molecules to complex macromolecules. It covers the properties of water, chemical bonds, and the structure and function of organic compounds essential for life, including carbohydrates, lipids, proteins, and nucleic acids.
Examples: C12 and C14 are isotopes of carbon. Both have 6 protons and while C12 has 6 neutrons; C14 has 8 neutrons. Electrons are negatively charged particles that are found in electron shells around the nucleus. They, (the electrons), determine the chemical properties of an element.

18 gru 2016 · The Elements of Life Overview. The overarching theme of Unit 1.2 is “The Elements of Life.” Before getting into the complex macromolecules that organisms need to survive, we must first understand that there are several elements that all life is dependent on: Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, and Phosphorus.
The following outline is provided as an overview of and topical guide to life forms: A (also spelled or ) is an that is living, [1][2] such as plants (flora), animals (fauna), and fungi (funga).
For example, the flow of blood within the circulatory system follows the laws of physics that regulate fluid flow. The breakdown of the large, complex molecules of food into smaller molecules—and the conversion of these to release energy to be stored in adenosine triphosphate (ATP)—is a series of chemical reactions that follow chemical laws.
