when a atom goes into the quantum transition by the electron jumping down a orbit, a photon is emited but wher does this photon come from (the laws of conservation of mass) and how does it get the signal to jump down a orbit?

The lower orbital has less energy. ("Lower" is a description of the energy) The rest mass of the atom is lower (and is not a conserved quantity). This has been experimentally confirmed in a nuclear transition; atomic ones are too small of a difference to measure.

thank, but how does the photon get emmited? does it just brake apart from the electron?

It's created in the interaction.

in the interaction of what? is it the energys of the orbit and electron that gives off throught photons?

The electron and nucleus interact (mainly) electromagnetically. The atomic energy levels are the result.

so the energy loss of the electron going down a orbit is givin of through a photon?

Yes.
