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.
What else can I help you with?
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
When an atom of 16N emits beta what does it make?
16O
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
What is an unstable atom that emits energy called?
This is a radioactive isotope.
What happens to the number of protons when U-238 emits an alpha particle?
When U-238 emits an alpha particle, it loses two protons. This results in the atom transforming into a different element (Th-234) which has two fewer protons in the nucleus.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
What change in atomic mass when an atom emits gamma radiation?
It remains the same.
How much does an atom's mass change when it emits gamma radiation?
An atom's mass does not change when it emits gamma radiation. Gamma radiation is a type of electromagnetic radiation with no mass or charge, so the total mass of the atom remains constant. The energy and momentum carried by the gamma radiation may cause the atom to recoil, but the mass of the atom itself does not change.
An atom that undergoes excitation and de-excitation emits?
An atom that undergoes excitation and de-excitation emits photons of light. When an electron in an atom absorbs energy and moves to a higher energy level (excitation), it eventually returns to its original state (de-excitation) and emits a photon of light corresponding to the energy difference between the two levels.
What happens to a nucleus if it gives off only gamma radiation?
A neucleas of an atom will become electricaly neutral becoze when it emits gamma radiations,gamma rays are neutral,it means that an atom will emit neutrons from neucleas,protons(positively charged pariicles)will cancel out electrons (negetively charged pareicles)& atom will become electrically neutral.
What happens to a metal atom when a splint soaked with chloride and placed in a flame and color is produced?
When a metal atom is heated in a flame with a chloride compound, the metal atom absorbs energy and is excited to a higher energy state. As the metal atom returns to its ground state, it emits light of a specific wavelength, resulting in the production of a characteristic color. This color can be used to identify the metal present in the compound.
What happens to atoms and their electrons while the entity emits light?
When atoms emit light, their electrons move to lower energy levels, releasing the excess energy in the form of photons. The photons emitted have a specific wavelength corresponding to the energy difference between the initial and final electron levels. This process is known as emission of light or photon emission.
