Chapter 3.4, 3.5, 3.6 Flashcards
What are the three components of naming covalent bonds when elements join together?
write elements in order in which they appear in the formula
prefix that indicates how many there are of each atom
if only 1 type of a certain element is used, the prefix mono can be used but only with the second element
What is the modified name of N (Nitrogen)
Nitride
What is the modified name of O (Oxygen)
Oxide
What is the modified name of F (Fluorine)
Fluoride
What is the modified name of S (Sulfur)
Sulfide
What is the modified name of Cl (Chlorine)
Chloride
What is the modified name of Br (Bromine)
Bromide
What is the modified name of I (Iodine)
Iodide

no
Do we use a prefix for naming covalent compounds or ionic compounds?
covalent
