Organic Chemistry Test 1 (Chapters 1,2) Atomic Number -number of protons Mass Number -protons + neutrons Isotopes -Same number of protons, different number of neutrons Aufbau Principle -electron goes into orbital of lowest energy Pauli Exclusion Principle -no more then two electrons can occupy an orbital and these electrons must be of opposite spins. Hund’s Rule -An electron will occupy an empty orbital before it pairs with an electron. Heisenberg Uncertainty Principle -precise location and momentum of an atomic particle cannot be determined. Octet Rule -an atom will give up, accept, or share electrons so that it can try to achieve eight electrons in the outer shell. Ionization Energy -energy to remove an electron from its orbital. Valence electrons -electrons in outermost shell Anion (-) -more electrons than protons Cation (+) -More protons than electrons. Ionic Bond -an atom loses or gains an electron Covalent Bond -an atom shares electrons.

Nonpolar Covalent Bond -Covalent bond between atoms of same electronegativity. Polar Covalent Bond -Covalent bond between atoms of different electronegativity. -S- = more electronegative -S+ = less electronegative Bond Polarity - arrow points toward most electronegative atom. Sigma Bond
