What happen when electron change energy level?
When an electron changes energy levels in an atom, it absorbs or emits energy in the form of a photon. This photon can have a specific wavelength corresponding to the energy difference between the initial and final energy levels of the electron. This process is fundamental to the emission and absorption of light in atoms.
When a beta particle is emitted does the mass number of the isotope remains unchanged?
With the ejection of a beta particle (electron), there is a minute loss of mass. Electrons have very low mass. The atomic number increases though as a neutron is transformed into a proton. A antineutrino is also ejected. In a similar process, positron emission also called beta decay,- a positron is emitted and a proton is transformed into a neutron, the atomic number decreases. A neutrino is also ejected.
What causes an electron to change energy levels within an atom?
An electron changes energy levels within an atom when it absorbs or emits a specific amount of energy, typically in the form of light or heat. This process is known as electron excitation or de-excitation.
Electron X can change to a higher energy level or a lower energy level Which statement is true of electron X?
Electron X can transition between energy levels by either absorbing or emitting a photon. The energy change corresponds to the photon's energy (ΔE = hf), where h is Planck's constant and f is the frequency of the photon. The transitions between energy levels are quantized and follow the laws of quantum mechanics.
Does transferring an electron change the identity of the elements involved?
No, transferring an electron does not change the identity of the elements involved. The number of protons in the nucleus, which determines the element's identity, remains the same. The transfer of electrons only affects the element's charge and reactivity.
How is the change in electron energy related to the frequency of light emitted in electron transitions?
Its right in the book (in bold) and has a key next to it.
When you changethe wavelength do you change the frequency?
No, changing the wavelength of a wave does not change its frequency. The frequency of a wave is determined by the source of the wave and remains constant regardless of changes in wavelength.
Why frequency of light never change when light changes medium?
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
What does the electron produce when they change energy levels?
When electrons change energy levels, they emit light or energy in the form of electromagnetic radiation. This emitted light can have specific frequencies or colors, depending on the difference in energy levels that the electron undergoes.
What happen to the speed when frequency and wavelength change?
It would change, depending on how much the frequency and the wavelength changes. It varies based on v = fλ.
Does the intensity of infrared waves emitted by the Sun change as the wavelength of the ultraviolet waves increases?
Yes, as the wavelength of the ultraviolet waves increases, the intensity of the infrared waves emitted by the Sun tends to decrease. This is because different wavelengths of electromagnetic radiation are emitted at different intensities by the Sun based on its temperature and composition.
If the frequency of a water wave changes what must also change?
The wavelength also changes.The product [ (frequency) times (wavelength) ] is the speed of a wave, which is constant.So in order for frequency to change, wavelength must change in the opposite direction, tokeep their product constant.
How is visible light made?
Light is emitted when an electron drops from the orbit of an excited state, into its natural state. The quantum of light emitted is characteristic of the change in energy of the two electron states, and also of the actual element involved.
What type of nuclear decay results in the atomic number increasing by one with no change in mass?
Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.
How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
What is the greatest change in wavelength in compton effect?
The greatest change in wavelength in the Compton effect occurs when the incident photon scatters off an electron at a 180-degree angle. In this scenario, the change in wavelength is at its maximum value, known as the Compton shift.
Why does wavelength change during refraction?
Wavelength changes during refraction because the speed of light changes when it passes through different mediums, causing the frequency to remain constant. According to the equation c = fλ (where c is the speed of light, f is the frequency, and λ is the wavelength), when the speed of light changes, the wavelength must also change to keep the frequency constant.
