Document Summary

What are the 4 classes of biomolecules that contain atoms of these elements: oxygen, nitrogen, phosphorus, sulfur, and carbon, carbohydrates, lipids, portions, and nucleic acids, describe the components of an atom and define an element. The number of protons determines the type of atom, called an element: the atomic number is the number above the element name on a periodic table. It represents the number of protons that element contains: the atomic mass number is the number below the element name on the parodic table it represents the number of protons and neutrons. For example, carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 has 8 neutrons: describe the types of bonds atoms can form to make a molecule. Include density when frozen, temperature moderation, evaporative cooling, cohesion and surface tension: in liquid water, hydrogen bonds are continually forming and reforming.
