Unit 3 Flashcards
Nonpolar Covalent
Electrons are shared equally by bonded atoms; balanced charge
Ionic Bond
When electrons are transferred between a metal and nonmetal
Covalent Bond
When electrons are shared between 2 nonmetals
Polar Covalent
Bonded atoms have an unequal attraction for shared electrons; unbalanced charge
Metallic Bond
Delocalized electrons move freely among positively charged ions
Polyatomic Ion
Charged group of covalently bonded atoms
Octect Rule
Outermost valence shell needs 8 electrons for stability
Oxidation Number
Number assigned to the charge of an ion in building compounds
Stock System
Uses Roman numeral to indicate ion’s charge
Electron Dot Notation
Only valence electrons of an element are placed around the element symbol
Nomenclature
A naming system
