Cell Biology 112 Exam 1 PCC 100% Correct

Cell Biology 112 Exam 1 PCC 100% Correct Induction Specific to general Deduction General to specific Archae/Bacteria Prokaryote. One-cell. No nucleus. Eukarya Eukaryotes. Multi-cell. Has a nucleus. Protons Found in nucleus. Positive charged. Nuetrons Found in nucleus. Neutral charge. Electrons Found in outer shells. Negative charge. Atomic Number Number of protons. Never varies. Atomic Mass Number of protons and neutrons in the nucleus. To determine number of nuetrons, subtract Atomic Mass from Atomic Number. Electron Shells Position of electrons. 1st electron shell. 2 electrons 2nd electron shell. 8 electrons. 3rd electron shell. 18 electrons. Octet Rule Seek 8 electrons. Will give, take, or share electrons in order to be happy. Orbitals 2 electrons per orbital. Valence Electrons Electrons in outer shell. Ionic Bonds Where an electron completely transfers to another atom. Ionic Compound Forms individual ions in water by separating (dissolving). Electrolytes Positive and negative ions connected together. Oxidation Loss of an electron. Reduction Gain of an electron. Covalent Bonds Sharing electrons, usually one from each atom. Covalent bonds result in molecules. Electronegativity How strong an atom
