Is it true that energy in the atom can be absorbed or released only in quanta of energy?
More or less. I have some quibbles about the wording, and it's also possible that it could simply increase its kinetic energy, which would not normally be considered an excited state.
If that's a homework question, the person who wrote it deserves 50 lashes with a wet noodle.
Restating it to remove ambiguities: "An atom may enter an excited state by absorbing energy." is definitely true.
What else can I help you with?
Energy stored in the nucleus of an atom is called?
Energy that is stored in the nucleus of an atom is called Atomic Energy or nuclear energy.
What does the change of an atom from an excited state to the ground state always require?
An atom emits a photon (particle of light) when transitioning from a ground state to its excited state. To obey conservation of energy, the energy gained by the atom when an electron moves to a lower energy level is equal to the energy it loses in emitting the photon. (The energy of a photon is E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon.) Conversely, when an atom absorbs a photon (as is the case in absorption spectra), the electron absorbing the photon moves to a higher energy level.
What happens to the electron as it moves closer to the nucleus?
An electron moving towards the nucleus slows down and any energy it contains from a higher shelf is released.
The release of light energy by particles of matter that have absorbed extra energy is called?
Light Emission. Re-emission phosphorescence and fluorescence are examples of processes that cause light to be emitted. When the electrons of an atom are excited to a higher energy level, they emit a quantum of light (photon) as the electron falls back to a lower energy level.
State and explain postulates of bohr's theory of hydrogen atom?
An essential point of Bohr's theory of the structure of the hydrogen atom was that only particular orbits with specific orbital energies are allowed. Another essential point was that energy is only absorbed or radiated by electronic transitions between these orbits.
Can energy in the atom be absorbed or released only in quanta of energy?
Yes only in quanta of energy
Can energy in the atom be absorbed or released in quanta of energy?
Yes. One well known example of this happens in LASERs and MASERs.
When an atom loses one or more electrons to form a positive ion the energy is?
When an atom loses one or more electrons to form a positive ion, the energy required is known as ionization energy. This is the energy needed to remove an electron from the atom.
Why do some photons travel right through the atom unchanged while others are absorbed?
Photons can travel through an atom without being absorbed if they do not have enough energy to interact with the electrons in the atom. However, if a photon has enough energy to match the energy levels of the electrons in the atom, it can be absorbed, causing the electron to move to a higher energy level or be ejected from the atom.
What type of energy lies at the level of an atom?
At the level of an atom, energy exists in the form of electromagnetic energy. This includes the energy associated with the movement of electrons within the atom and the energy released or absorbed during processes like electron transitions or photon emissions.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
When energy goes into an atom is light produced?
When energy is absorbed by an atom, the electrons in the atom can jump to higher energy levels. When they return to their original positions, they release the extra energy in the form of light. This is how light is produced in an atom.
Is energy absorbed or released to form positive ions?
Energy is typically absorbed to form positive ions through ionization. This process involves removing an electron from a neutral atom or molecule to create a positively charged ion. The energy required to remove the electron is known as ionization energy.
If you make the electron jump downward then return it to the outer ring what do you notice about the photon released or absorbed?
When an electron jumps downward to a lower energy state in an atom, it releases energy in the form of a photon which is emitted. When the electron returns to the outer ring, it absorbs energy in the form of a photon. The energy of the photon absorbed is equal to the energy of the photon released during the downward jump.
The spectral lines in the spectrum of an element relate to the?
The energy levels of the atom; from which when the atom is in an exited state and drops down in to a lower energy level it releases a quanta (packet) of energy which is of a certain frequency, this is then related to the colour of the light released.
When electrons move from a high energy excited state to a low energy ground state. E Energy is absorbed by the atom?
No, energy is released by the atom when electrons move from a high energy excited state to a low energy ground state. This energy is emitted in the form of light or heat depending on the specific energy level transition. The difference in energy levels determines the wavelength of the light emitted.
What happens when photon is absorbed by atom?
When a photon is absorbed by an atom, it can excite an electron to a higher energy level or even ionize the atom by completely removing an electron. This absorption of energy can cause the atom to undergo various processes such as fluorescence, photoelectric effect, or photoionization, depending on the energy of the photon and the characteristics of the atom.
