It is actually the nucleus of the atom that emits energy. The energy we can harness comes from fission or splitting of the nucleus of uranium235 or plutonium239. The nucleus splits into two parts which recoil and give up their kinetic energy as heat when they are stopped in the fuel, and there is also some energy from gamma rays at the same time. Basically in the process the final results of the fission have lost mass, and this appears as energy following the relation E = M x C2.
Atoms can also emit energy as radioactivity, without fissioning. This can be alpha, beta, or gamma radiation. Alpha and beta are particles, so that the resulting nucleus is changed and there results a different element. Gamma is a penetrating ray in the electromagnetic spectrum and corresponds to a change in the energy state of the nucleus, but it remains the same element.

∙ 16y agoWhen an atom absorbs energy the electrons orbiting that atom move into a higher energy orbit. In this way the energy is stored until it is later released causing the electrons to return to a lower energy orbit.

∙ 14y agoTwo main things can happen:
1- The energy of the photon is high enough that it will make the atom expell an electron - that is, the energy of the photon is equal or greater than the current ionization energy of the atom;
2- The energy of the photon is not enough to make the atom expell an electron, and thus the photon will just make the electron circle a bit further from the nucleus - that is, if the photon has a energy equal to the difference of energy between two orbitals, then the atom will absorb the photon, and the electron will go to the higher energy orbital, further from the nucleous.

∙ 16y agoThe energy from the photon causes the electrons to move up in energy levels.
Because the electrons absorb all the energy.

∙ 9y agoWhen an atom absorbs energy it can cause different effects but most likely it will re-emit the energy as light. The atom will also move into a higher orbit.

What happens after an atom stores energy from passing electrons?
The energy is eventually released as light.
How does an excited atom get to a ground state?
For example, by the absorption of a photon.
What happens when a magnesium atom loses an atom in its outer energy shell?
l
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
Describe what happens to the outermost electron in a sodium atom when the atom is heated and made to give off a line spectrum?
the atom jumps up the the higher energy level and as it returns to the lower energy level it releases energy which turns into light
What happens when hydrogen atom absorbs a quantum of enery?
The electrons move up to a higher energy level.
What happens when electrons absorbs energy?
When an electron in an atom absorbs a specific "Quantum" of energy, it will jump to the next specific energy level in the atom. It'll then jump back down, and in so doing releasing light and giving off a signature light spectrum for an element.
What happens when an electron in an atom absorbs energy?
When an electron in an atom absorbs a specific "Quantum" of energy, it will jump to the next specific energy level in the atom. It'll then jump back down, and in so doing releasing light and giving off a signature light spectrum for an element.
What happens when photon is absorbed by atom?
When an atom absorbs a photon its energy is transferred to outer shell electrons. The result will be the transition of an electron to a higher energy state.
What is a possible result of an atom that absorbs sufficient energy?
The atom may emit a photon.
What happens when you break a hydrogen atom?
it absorbs a lot of heat.
When an atom absorbs energy that causes one of its electrons to move to a higher energy level the atom is said to be in?
Excited state
When does an electron go from the ground state to an excited state?
When the atom absorbs energy of the proper frequency/energy.
What happens to an object when it absorbs light energy?
heats up
What happens when a molecule absorbs ultraviolet radiation?
When oxygen absorbs UV, it breaks it down. That atom then reacts again with oxygen to form ozone.
What does incident light that falls on an object do to the electrons in the atoms of an object?
When a photon of energy falls on an electron bound inside an atom, the electron absorbs the energy and is emitted from the atom.
What happens when a kinetic energy transferred from object to object?
it absorbs it and passes it on.
