How do you calculate the energy released or absorbed in the electron jump n1 to n3?

It can only be calculated easily for a one-electron atom or ion (for instance H, He+, Li2+, etc.). For a one electron atom, it is quite easy to calculate. If the electron is starting at n = 1 and going to n =3, then energy will be absorbed by the atom. If it is the opposite, starting at n = 3 and going to n = 1, then energy will be released.
The equation is called the Rydberg Formula:
E = RH * Z2 * (1/ni2 - 1/nf2)
where E is the energy
RH is the Rydberg constant = 13.6 eV
Z is the charge of the nucleus (# of protons)
ni is the initial level of the electon
nf is the final level of the electron
See the Web Links for more information about the Rydberg formula.

What is the name of the enzyme that produces ATP in the electron transport chain?
absorbed light energy or sunlight.
When molecules are broken down from where is the energy released?
When molecules are broken down the energy is released from the outer electron shells of the various elements involved.
Is the energy absorbed or released during the process in photosynthesis?
Photosynthesis is an uphill reaction, meaning it is energy absorbing. Respiration is a downhill reaction so it is energy absorbing.
Why formation of anion is exothermic?
During the Formation of postitve ion we have to break the force attraction between nuecleus and electron. while doing so energy is absorbed and process become endothermic.
What is the term for Heat taken or released in a dissolving process?
I suppose that these are synonyms.
When an electron gets excited is energy released or absorbed?
To get excited, it must absorb energy. To get back to its ground state, it releases energy.
What is it called when absorbed light energy is released by matter?
Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...
When an electron falls back to its ground state how much energy is released?
It releases the same amount of energy that it absorbed when it was excited to a higher energy state.
An electron that has absorbed energy?
excited state
Is energy absorbed or released to form positive ions?
It always requires energy to pull an electron from a neutral atom and form a positive ion.
If an electron has absorbed energy and has shifted to a higher energy level the electron is said to be what?
This electron is called excited.
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
What can be said of the amount of energy that an electron absorbs when it is excited compared to the amount of energy that it releases when it returns to ground state?
The amount of energy that is absorbed is the same as the amount of energy that is released.
When absorbed light energy is released by matter it is called what?
Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
Is energy absorbed when an electron moves to a closer shell?
No. Energy is emitted when an electron moves to a closer shell (closer to the nucleus).
When electron hits any wall like thing will it lose all its energy?
The electron does not lose its energy. The electron gets absorbed by the "wall" and the electron/energy becomes part of the "wall" system.
