QuestionAnswer
Cations Positive Ions/Formed by losing electrons/more protons than electrons/only metals
Anions Negative ions/formed by gaining electrons/usually non-metals
Monatomic Ions Ions formed from a single atom/ -ide
Polyatomic Ions Ions formed from two or more atoms/ -ate, -ite
Binary compounds More than two elements
Nomenclature Naming system of binary ionic compounds which involves combing the names of the compound's positive & negative ions/ cation followed by ion
Stock System of Nomenclature Used to distinguish the ions formed by elements that form two or more cations with different charges/only used with cations
Oxoanions polyatomic ions that contain oxygen
Molecular Compounds composed of individual covalently bonded units or molecules
Oxyacids acids that contain hydrogen, oxygen, and a third element
Binary acids Acids that consist of two elements, usually hydrogen and another halogen
Hydrochloric acid a water solution of the molecular compound hydrogen chloride, HCI
Salt an ionic compound composed of a cation and the anion from an acid
Oxidation numbers used to indicate the general distribution of electrons among the bonded atoms in a molecular compound or a polyatomic ion assigned to the atoms composing the compound or ion
Atoms electrically neutral particles
Ions different number of protons vs electrons (positive or negative charges)/ made by electrons moving
Group B Elements many transition element have more than one possible oxidation state
Ionic Compound compounds with metals
Covalent Compound compounds formed of only non-metals
Molecular Mass the mass of a molecule
Formula Mass the sum of the average atomic masses of all atoms represented in the formula of any moleculy/formula unit/ion
Percentage Composition the percentage by mass of each element in a compound is known as this compound
Empirical Formula the smallest whole number ratio of atoms in a compound
Molecular Formula (True formula) the actual number of atoms in a compound
