BIOL 1201 : Biology Exam 1 Video Notes
Document Summary
Reductionist approach- study individual parts very in depth. Wholist approach- start with studying the entire structure or organism. The structure of the elements that we are built of makes iife vs just a pile of those elements. Smallest unit of matter separable by normal chemical means. The smallest unit of matter that retains all of the properties of that particular element. Equal to the number of protons in an atom and electrons of a neutrally charged atom. Equal to the number of protons and neutrons. Isotopes-variants of an atom in that they have a different number of neutrons. The number of electrons that need to be gained or lost to fill the outer shell of electrons. Valence also predicts the number of bonds that an atom will form. Form when atoms gain and lose or share electrons. They are the result of electrical attractions between atoms: ionic bond- form when atoms completely gain or lose electrons strongest bonds when dry.
