When considering atomic orbitals the only important information they really wanted to know is the size of the orbit, which was described by using quantum numbers.
A synthesis would be A+B-->AB its combining, decomposition is AB-->A+B, its the breaking up of a substance.
The more acidic the substance is, the more the iron nails will corrode (this obviously depends on what your experiment is but hope this helped in some way)
The answer is AIM NOT POSTIVE
