Bohr's Model Atom

Bohr was a scientist who found the current atomic structure and quantum theory. Basically mean that a atom's Protrons and Neutrons circle the atom's Nucleus. Here's a Bohr's Model Oxygen.

Balancing Equations

Basically when you have a Equation you'll see little numbers below the Atom in a equation those are called Coefficients. Here's what a Chemical Equation looks like basically to balance it you have to find the LCM or Least Common Multiple of all the coefficients in the equation.
