The dichromate ion is Cr2O7-2. Ammonium dichromate is two ammonium ions and one dichromate ion (to balance charges- ammonium has a +1 charge and dichromate has a -2 charge): (NH4)2Cr2O7. Therefore, ammonium dichromate would contain 7 oxygen atoms.
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.

It's ammonium dichromate.
It is a chemical change because the ammonium dichromate changes color, explodes, and probably creates a gas during the change.

Aluminum dichromate has the formula unit of Al2(Cr2O7)3. This means there are two aluminum, six chromate and 21 oxygen atoms present for a total of 29 atoms.
Ammonium dichromate decomposes while burning to Nitrogen, Water and Chromium(III) oxide.(NH4)2Cr2O7 ----> N2 + 4 H2O + Cr2O3
Either ammonium nitrite or ammonium dichromate can he heated to obtain nitrogen gas.
