- 1Electron Shells-shell models are diagrams in which the electrons are shown orbiting in concentric circles (electron shells) and around the nucleus
-similar elements will have the same amount of electrons in their outer shell - 2Patterns in atomic structure-the atoms in each new period of the periodic table have an additional electron shell
-the arrangement of atoms in the periodic table reflects the arrangement of electrons in the atom - 3Valence Shellthe outermost shell that electrons occupy
- 4Valence electronsthe electrons that occupy the outermost shell
- 5Core Electronsthe electrons that are located in all of the other shells that are not the very outer one
- 6Noble Gassesnoble gasses are the most chemically stable elements, this is because they have a full outer shell
- 7Ions-an atom or group of bonded atoms that has a positive or negative charge
-when an atom loses or gains electrons, the result is a charge on the atom, the rest of the atom stays the same and the identity of the atom does not change - 8Anionsions with a negative charge
- 9Cationan ion with a positive charge
- 10Ionic Compounda compound that consists of positively charged metal cations and negatively charged nonmetal anions formed when valence electrons are transferred
- 11Rule of zero chargethe rule that states that in an ionic compound, the positive charges of the metal cations and the negative charges of the nonmetal anions add up to zero
- 12Urban Resiliencea city's ability to bounce back after acute or chronic stresses
- 13Noble Gas Envyall other elements are envious of noble gasses because they have eight electrons in their outer shell. to satisfy NGE, elements become ions
- 14Predicting Chemical Formulas (for salt compounds)1. make sure you are combining two different elements- a metal and a nonmetal
2. no matter how many you use, the total number of valence electrons must add up to 8 or any multiple of 8
3. Make sure that the charges on the metal cations and the nonmetal anions in your ionic compound add up to zero - 15Salt Compoundsan ionic compound that is made up of one metal and one nonmetal
- 16Naming Ionic Compoundsin salt compounds, the name of the metal comes first, followed by the name of the nonmetal atom. the end of the nonmetal atom is altered by adding "-ide"
- 17Polyatomic Ionan ion that consists of two or more atoms covalently bonded
- 18Monatomic Ionan ion that consists of only one atom
- 19Electron configurationa notation for keeping track of where the electrons in an atom are distributed among the shells and subshells in an atom
- 20Dissolveto disperse a substance homogenously into another substance at the molecule, ionic, or atomic level
- 21Solublecapable of being dissolved into another substance
- 22Insolubleunable to be dissolved into another substance
- 23Conductivitya property that describes how well an substance transmits electricity, heat, or sound
- 24Ionic Bond-metals lose electrons
-neutral charge
-stable
-will be solid at room temperature - 25Covalent Bond-molecule
-shares electrons
-always between two or more nonmetals
-water is a covalent bond
-state of matter: gas or liquid - 26Metallic Bond-between metals
-all share electrons
-shininess is a result of the electrons being shared - 27Network Bond-diamond is an example of a network bond
-not conductive
-shared symmetrically with its four neighbors - 28Oxidation #the charge of an atom when it's by itself
