Why does this model only work for central atoms with no lone electron pairs?
a. The electron pairs don't exist on molecules because all electrons
are covalently bonded to the rest of the atoms in the molecule.
b. The electron pairs are not visible as bonds, but they act like bonds
in terms of shaping the molecule.
c. Electron pairs only exist on external atoms, not central atoms.

what are the two models

explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
