What happens to the average distance between the atoms when the copper is heated?
Not entirely sure but I will find out and tell you! :)
How many copper atoms does it contain The volume of a sphere is 43pieR3 and the density of copper is 8.96 gcm3 A pure copper sphere has a radius 0.936 in?
Use your volume formula and your radius to find volume. Next use the equation d=m/v or m=dv to find your mass of copper. Use your mass, atomic weight of copper, and avagadro's number to figure out your atoms.

What is the atomic weight for copper?
Copper can be found on the Periodic Table of Elements. Copper's symbol is Cu, and the atomic number is 29. The atomic mass is hard to find searching the Internet, but here it is. The atomic mass for Copper is 63.546, also recognized as just 63.Atomic Number: 29Atomic mass: 63.546, or just 63**Note: The atomic mass for Copper and some other chemicals cannot be found on WebElements.
How many atoms in 8 grams of copper?
Actually, it depends very much on how big your piece of copper is, but in just a small coin made of copper, you can actually find many billions or even trillions of atoms of copper. Extra fact: Atoms of elements are actually so small that their atomic radii are measured in pico meters (1pm=1x10-12m)

Look down at the link "Atomic structure of silicon atoms". There you will find the atomic structure of silicon atoms.
What atoms of which elements would you find in copper sulfate?
Copper Sulfate is CuSO4. Therefore, it has 1 atom of Copper, 1 atom of Sulfur, and 4 atoms of Oxygen.
How many atoms are there in a 1cm cube of copper?
Find the mass of 1 cm3 of copper.density= mass / volumemass= density * volume (density is about 8.96 g cm-3)mass= 8.96 g cm-3 * 1 cm3 = 8.96 gno. of moles = mass / Molar mass =8.96 g / 63.5 g mol-1 = 0.14 molno. of copper atoms in 1 cm3 of copper= 0.14 mol * 6.022 *1023 =8.4 * 1022 atoms

How do you find the protons and neutrons in bromine?
To find the protons in Bromine, atoms always have the same number of protons as their atomic number, so since Bromine has an atomic number of 35, it has 35 protons. To find the average number of neutrons in Bromine, you take the the atomic mass and take away the number of protons (in this case 35), so since Bromine's atomic mass is 79.90, you take away 35 to get the number of neutrons. The average number of neutrons in Bromine is 44.90.
How do you find the atomic mass of C7H8?
You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.
