naming compounds Flashcards
composed of two elements
binary compounds
metal-nonmetal
binary lonic compounds
nonmetal-nonmetal
binary covalent compounds
binary ionic compounds contain
positive cations and negative anions
metal present forms only one cation
type 1 compounds
metal present can form 2 or more cations with different charges
type 11 compounds
rules for naming type 1 lonic compounds
-the cation is always named first and the anion second
-a simple cation takes its name from the name of the element
-a simple anion is named by taking the first part of the element (the root) and adding -ide
metals in these compounds can form more than one type of positive charge
binary lonic compounds
roman numerals indicates
the charge of the metal cation
transition metal cations usually require a
roman numeral
