3. If the radius of a potassium atom is 2.48 x 10-7 mm, how many K atoms would fit along the edges of a circle
with a circumference of 3.75 inches?
4. Naming Practice
A. Copper (I), Cu, reacts with oxygen, O, to give an ionic compound. Name and write the formula for this
ionic compound. Name and write the symbols for the cation and anion in this compound.
B. What is the formula for tetrasulfur tribromide? Is this covalent or ionic? How can you tell?
C. For the compounds in A and B write all possible mole:mole relationships. For example, for water you
can write three relationships, 2 moles H atoms = 1 mole H2O molecule, 1 mole O atom =1 mole H20
molecule, 1 mole O atom = 2 moles H atoms
