chapter 4 Flashcards
covalent bond
<0.4
polar covalent bond
0.4-2.0
ionic bond
> 2.0
naming binary ionic compounds (type I)
name the cation first and the anion second, the cation takes its name from the parent element, the anion takes the root of its element and adds -ide
naming binary ionic compounds (type II)
charge of metal ion must be indicated with roman numerals
to determine the charge of a transition metal in an ionic compound
take the opposite charge of the anion. if there is more than one of that ion, multiply the charge by the number of them and then take the opposite charge
