Answer | Question |
Chemical Bond | Mutual electrical attraction between nuclei and valence electrons of dif. atoms that bind together to make stable and happy atoms |
Ionic Bonding | Chemical bond that is caused by cats and onions combining to become neutral and with out stench |
Covalent Bonding | Chemical Bond in which electron pairs are shared between 2 unhappy atoms to make both happy (2 atoms of same element) |
Polar covalent | Unequal pull on electrons that are covalently bonded (.3 and 1.7), balanced distribution of the electrical charge |
Non polar Covalent | Each atom has equal attraction to the electrons (less than 3), unequal distribution of the electrical charge |
Molecules | Neutral group of atoms that are held together by covalent compounds |
Molecular Compound | Chemical compound whose simplest units are molecules |
Formation of Covalent Bonds | Nuclei and electrons attract each (decreasing the potential energy) while the 2 nucleus and electron clouds repel (increasing potential energy) |
Ionic Compound | Positive and negative ions that are combined so that the number of + and - charges are = |
Formula Unit | Simplest collection of atoms from which an ionic compound formula can be established |
Lewis Structures | formulas representing the atomic symbols of atoms bonding relationships |
Lattice Energy | Energy that is released when a separated ions come together in a crystal structure from a gas |
Polyatomic Ions | Charged group of covalently bonded atoms, that add or loose electrons to become one with the world |
Metallic Bonding | Chemical bonding that results from the attraction between metal atoms the surrounding sea of electrons |
Metallic Properties | Conductors/ reflector of light/ absorber of light/ Malleable/ Ductile |
Metallic Bond Strength | Depends on nuclear charge and number of electrons, effects the enthalpy of vaporization |
Diatomic Molecules | When atoms bond there is a specific shape created, it must be linear because there are only 2 atoms |
Hybridization | explains how orbitals of an atom become rearranged when the atom forms covalent bonds- produce a new hybrid atomic orbitals of equal energy |
Intermolecular Forces | Attractive forces that vary in strength, and are generally weaker than bonds that join atoms in molecules |
Dipole | Created by equal and opposite charges that are separated by a short distance |
Dipole-Dipole | created by unequal charges, separated by short distances, between polar molecules |
Induced Dipole | Induce a non-polar molecule to become temporarily polar by attracting its electrons |
Hydrogen Bonding | Intermolecular force in which the hydrogen atom (which is bonded to a highly electronegative atom) is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule |
London Dispersion Forces | Intermolecular attractions resulting from the constant motion of electrons and the separation of induced dipoles/ increase with atomic mass |
