What else can I help you with?
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
Why does the emission of carbon dioxide poses threat near volcanic eruptions?
In some cases the emission of a large amount of carbon dioxide can displace oxygen from the air. As a result, people and caught in the gas cloud can asphyxiate.
What happens to the atomic mass and number during gamma ray emission?
The atomic number and atomic mass number do not change as a result of gamma emission. That said, gamma emission is the result of the nucleus stabilizing itself from an excited state that was caused by some event, such as an alpha, beta, neutron, or some other kind of emission. As a result, when you look at the big picture, the atomic number and atomic mass number do change as a function of the event preceding the gamma event. The only time this is a distinct event is in the metastable nuclides, such as Tc-99m, where the gamma emission that follows the beta- emission does not immediately follow it - it can be delayed with a half-life of six hours.
Why cant an atom in the ground state produce emission lines?
An atom in the ground state does not have any electrons excited to higher energy levels. Without these excited electrons transitioning back to lower energy levels, there is no emission of photons with specific wavelengths that correspond to emission lines.
When the electrons of an excited atom return to a lower energy state the energy emitted can result in the production of what?
When the electrons of an excited atom return to a lower energy state, the energy emitted can result in the production of light, in the form of photons. This process is known as emission spectroscopy and is used in various analytical techniques to identify elements or compounds based on their characteristic emission spectra.
Does alpha radiation results in the emission of electrons?
No, alpha radiation does not result in the emission of electrons. It involves the emission of alpha particles, which are helium nuclei consisting of 2 protons and 2 neutrons.
What is the result of combining an acid with a carbonate?
The most obvious effect is the emission of carbon dioxide.
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
What are the effect of field emission?
Field emission can result in the emission of electrons from a material's surface when a strong electric field is applied, leading to current flow in a vacuum or low-pressure environment. This phenomenon is used in technologies like field emission displays and electron microscopy. It can also lead to material degradation due to the loss of surface atoms during emission.
Explain the effect of the nitrate ion in solution on the color emission?
The presence of the nitrate ion in solution typically does not have a direct effect on color emission. Nitrate ions are typically colorless and do not absorb visible light that would result in color emission. However, in some cases, nitrate ions can indirectly affect color emission by participating in complex chemical reactions that result in color changes.
What is the perpose of an exhaust emission system?
To help clean up the emissions that come out of the exhaust, the result, cleaner air.
Why does the emission of carbon dioxide poses threat near volcanic eruptions?
In some cases the emission of a large amount of carbon dioxide can displace oxygen from the air. As a result, people and caught in the gas cloud can asphyxiate.
When an object is heated to higher temperatures what happens to its wavelength of emission?
When an object is heated to higher temperatures, its wavelength of emission decreases. This is because higher temperatures result in higher energy levels of emitted photons, corresponding to shorter wavelengths. This phenomenon is described by Wien's displacement law.
How does Neutron emission from a nucleus affect an element?
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
How can spontaneous emission be control?
That's why it's called spontaneous emission you cannot control it. But there is a kind of emission which is called stimulated emission emission. People use stimulated emission in lasers and it can be controlled.
What are 4 methods of electron emission?
1- Secondary Emission 2- Thermionic Emission 3- Field Emission 4- Photo-Electric Emission Badbanky
Is emission of light always associated with heat?
No, emission of light is not always associated with heat. Some processes, like bioluminescence in certain organisms, can result in the emission of light without generating significant amounts of heat. Additionally, light-emitting diodes (LEDs) also produce light without generating much heat.
