What else can I help you with?
Why cant you add the average masses of each of the isotopes and divide to get overall average of the atoms?
Because the isotopes do not appear in equal amounts. This is hardly surprising since many isotopes experience radioactive decay and change to other elements after decay while stable isotopes persist - thus stable isotopes will usually dominate as the most common isotopes for individual elements with those with the longest half-lifes being more common than those with shorter half-lifes. Of course when you get into the heaviest elements there don't seem to be any stable isotopes so those with longest half life dominate.
What is the atomic number the atomic mass and the number of neutrons of the element hydrogen?
The 'standard' hydrogen atom has atomic number 1, atomic mass 1, no neutrons. Although there are 2 other isotopes of hydrogen: - (cant confirm name) which has atomic mass 2 and 1 neutron. - (cant confirm name) has atomic mass of 3 and 1 neutron. All isotopes have atomic number 1.
How many atoms in PVC?
We make atomic number by number of protons in a atom. PVC is not single atom. We cant give it a atomic number.
How cant you tell isotopes of the same element apart?
You can tell isotopes apart by the difference in there atomic mass numbers. Take for example the isotope Carbon-12. Carbon is the element name and 12 is the atomic mass of the element. The atomic mass number can (most?) always be changed, but the the atomic number ( the number above the Element symbol on the Periodic Table) cannot. Remember: The number of protons add by the number of neutrons equals the atomic mass number. The proton number = the atomic number, as of the number of electrons= the atomic number; hence the atomic number= number of proton = number of electron.
How are atoms and molocules related?
Atoms are the building blocks of molecules. Molecules are formed when two or more atoms chemically bond together. Different combinations of atoms can create a wide variety of molecules with unique properties.

What is a pure substance composed of atoms with the same number of protons and cant be broken down?
A chemical element.

You cant
Which prime number is a even number?
2 is an even but prime number because it cant be divided by its self or by any other number.
