We’re being asked to write a chemical formula for each of the given molecular compounds.
A covalent or molecular compound is composed of more than one nonmetal together.
Rules for naming molecular compounds:
1. The first nonmetal is named normally and uses numerical prefixes except mono.
2. The second nonmetal keeps its base name but has its ending changed to -ide.
Mono 1 Di 2
Tri 3 Tetra 4
Penta 5 Hexa 6
Hepta 7 Octa 8
Nona 9 Deca 10
*numbers are written as subscripts of the element in the chemical formula
Write a formula for each of the following molecular compounds. Express your answer as a chemical formula.
a. radon tetrafluoride
b. tetraphosphorus decoxide
c. xenon tetrafluoride
d. diboron trioxide
e. iodine monobromide
