Isotopes and Atoms

Okay, sorry for the late post but here it is, isotopes and atoms. Let's start with the basic definition of an atom.
Atom-- the smallest unit of an element, having all the characteristics of that element
Simple right?
Now i realize that the scientific atom might not seem as interesting as this guy right away but it can be quite amazing. (but maybe not quite so much right now)
 
and now a couple formulas you need to know
Atomic Number = Number of Protons
Atomic Mass- Atomic Number = Number of Neutrons
Where to find these numbers you're wondering? Well you can find them right here.

The 6 in the upper left corner represents the Atomic Number
The =/-4 represents the charge (it's not particularly important for this though)
The C is the symbol for Carbon
The 12amu represents the mass (in atomic measuring units)






However not all atoms of the same element are identical some have a different mass these are called isotopes
An Isotope has the same Atomic Number as the atom it represents but a different mass.
For example
 This is a Carbon isotope. When writing isotopes you see the two numbers in front of the C, the top number is the mass number, the bottom is the atomic number. Same atomic but different mass number.
Easy right.
Thus we shall finish off with a couple of comics. On chemistry related and the other not so much.
