Why energy is released during the addition of first electron into oxygen atom?
MansoorKhalid
Even though an oxygen atom is electrically neutral, since it has equal numbers of protons and electrons, it can still act as though it is positively charged, because the electrons are very mobile and they arrange themselves in a way that maximizes their connection to the nucleus while minimizing their connection to other electrons, which repel them. So when an oxygen atom adds an electron, that electron is attracted by the positive nucleus more than it is repelled by the negative electrons orbiting the nucleus. The separation between the electron and the nucleus is a form of potential energy, just as you gain potential energy by raising an object in a gravitational field. As the electron falls toward the nucleus, potential energy is converted into other energy, such as heat or light.

The energy released during the ionization of a non-metal is called the?
ionization energy
When an electron drops from a higher energy level to a lower energy level is it taken from the environment?
No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.
Why formation of di and tri-negaive ions is endothermic process?
when an electron is added to an atom, uninegative ion is formed and enrgy is released. the addition of one more electron is difficult because negative charge or electronic cloud repels it strongly, to overcome this repelsion an amount of energy is needed, which is obtained by surroundings so its an endothermic reaction.
What is the amount of energy released by an electron as it returned to ground state?
An excited electron releases a photon as it returns to ground state.
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.
During what is electrons transferred and energy is released?
Electron transport chain
The energy released during the ionization of a non-metal is called the?
ionization energy
What happens to an electron during an electron transition?
Drops to a lower energy level and emits one photon of light.
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
Why is energy absorbed during successive electron affinities?
There is a greater repulsive force from the negatively charged anion, thus causing the addition of successive electrons to be electrically unfavorable. Energy is necessary to overcome the electrostatic repulsion, making additional electron affinities endothermic. For the same reason, the noble gases and nitrogen absorb energy even for their first ionization energy. Greater stability = energy released. It requires energy to disrupt that stability.
Energy lost by an electron during its transition from an outer to an inner orbit is emitted as a flash of light called a?
Energy lost by an electron during its transition from an outer to an inner orbit is emitted as a flash of light called an emission. Light/energy emissions are released in a characteristic manner (wavelength) that corresponds to the amount of energy lost.
When an electron drops from a higher energy level to a lower energy level is it taken from the environment?
No, the energy released by electron might be taken by enviornment. Electron remains in the infuence of corresponding nuclei, in another energy level.
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.

Where does an electron move after a photon is released?
lower energy level
What is the amount of energy released by an electron as it returned to ground state?
An excited electron releases a photon as it returns to ground state.
Is energy released or energy absorbed during condensation?
thermal energy is released during condensation.
