Iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction
natulia [17]

iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction - comparatively speaking, ferrous compounds are easier to hydrolyze than their ferric counterparts.

<h3>What is Redox reaction ?</h3>

Compared to ferric oxide, ferrous oxide is more basic in makeup. Comparatively speaking, ferrous compounds are more ionic than their ferric counterparts. Due to the fact that ferrous compounds are more ionic than their corresponding ferric ones, they are less volatile.

The greater positive charge of ferric compounds, however, makes them easier to hydrolyze than the comparable ferrous ones.

The quantity, kind, and distances of the iron atom's neighbors all contribute to their stability. Because each Fe atom is only weakly linked together by three electrons, which makes them susceptible to being dragged away by strong electronegative neighbors like oxygen, both types of ions are stable.

The photon of light that is emitted as an electron drops back to its original orbit is:
Alex73 [517]

Answer:

energy

Explanation:

The photon of light that is emitted as an electron drops back to its original orbit is energy and this energy is released during de-excitation process.

The electron is jumped into higher level and back into lower level by absorbing and releasing the energy.

The process is called excitation and de-excitation.

Excitation:

When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.  For example if electron jumped from K to L it must absorbed the energy which is equal the energy difference of these two level. The excited electron thus move back to lower energy level which is K by releasing the energy because electron can not stay longer in higher energy level and comes to ground state.

De-excitation:

When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum
