An element is selective in the frequency of light it will absorb This selectivity is due to its?
Every element can only absorb certain wavelengths of light because of how the electrons are positioned around the nucleus. There is a fixed number of energy levels that each electron may move to, and each move will only occur if a specific amount of energy is absorbed. Thus each element, having differing electron orbital states can only absorb certain frequencies of light.
If a solution reflects white light does it absorb all wavelengths?
No, a solution that reflects white light does not absorb all wavelengths. Instead, it reflects most of the wavelengths within the visible spectrum which combine to form white light.
What happens when an electron emits a photon?
When an electron absorbs a photon, the energy it gains can cause it to change orbitals. The result is ionization. The electron can then emit a photon in the process of "falling back" into its original orbit. Note that electrons won't absorb a photon that cannot give them enough energy to reach a higher orbital. There are no "half measures" in this aspect of quantum mechanics as electrons cannot be shifted "half way" to the next higher orbital. The proof of the pudding here is that we can use lasers of a given frequency to stimulate the electrons in orbit around given atoms. By knowing how much energy a certain electron needs to move to the next higher orbital, we can tune our laser to that photonic energy. Then when we point our laser at a bunch of these atoms, we'll see a bunch of electrons being kicked up to higher orbitals and then emitting photons to return to their previous orbital. There is a bit more to this, but the essentials are here, and are a first step to understanding the subtle ways photons and electrons interact.
What happens when an electrons jumps from one energy level to another?
When an electron jumps from one energy level to another, it either absorbs or emits energy in the form of a photon. This process is called an electron transition and is responsible for the emission or absorption of light in atoms. The difference in energy between the initial and final energy levels determines the wavelength of the emitted or absorbed light.
When an electron gets excited is energy released or absorbed?
When an electron gets excited, energy is absorbed to move the electron to a higher energy level. This absorbed energy gets released when the electron returns to its original energy level, emitting electromagnetic radiation such as light.
Which physical charateristic of a solution may indicate the presence of a transition element?
The color of a solution can indicate the presence of a transition element. Transition metals often exhibit vibrant colors in solution due to the presence of d-orbitals that can absorb and emit light in the visible range.
Which physical characteristic of a solution may indicate the presence of a transition element?
The color of a solution can be a physical characteristic that indicates the presence of a transition element. Transition metals in solution often exhibit distinct colors due to their ability to absorb specific wavelengths of light, leading to colored solutions.
Which ion in manganese nitrate is responsible the compounds colour?
Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
When an electron in the ground state absorbs energy what happens?
jumps to the a higher orbital. This is only possible if the energy it absorbed is large enough to let it jump the gap. If the energy is not large enough for the electron to jump that gap, the electron is forbidden to absorb any of that energy.
Why is the aqueous solution of Cu2 plus blue?
The aqueous solution of Cu2+ ions appears blue due to the absorption of certain wavelengths of light. The blue color is a result of the d-d electron transitions within the copper ions, where the electrons absorb energy and transition to higher energy levels, leading to the absorption of specific colors in the visible spectrum, giving the solution its characteristic blue color.
How light is absorb?
By the agitation of an electron by a photon.
Why is silver a transition metal?
Yes Silver (Ag) has atomic number 47. It is in column 11 (IB) Those elements in the middle of the chart, as well as the Lanthanides and Actinides are considered Transition Elements (metals).
Which element group form colorful compounds?
Transition metals, such as those in groups 3-12 of the periodic table, are known for forming colorful compounds due to their ability to absorb and reflect different wavelengths of light. The presence of unpaired d electrons in transition metals allows them to participate in various electron transitions, resulting in vibrant colors in their compounds.
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
Can free electron absorb photon?
Yes, free electrons can absorb photons. When a photon interacts with a free electron, it can transfer its energy to the electron, causing it to move to a higher energy level or even be ejected from the material. This process is the basis for various phenomena such as photoelectric effect and Compton scattering.
What is needed to excite electrons?
For example when the electron absorb energy.
Why specific solution absorb at specific wavelength?
It has to do with the energy level accessible to the electron in a particular type of bond or orbital. The difference between the two energy levels determines the energy of the quantum step and consequently the frequency of the light absorbed or emitted.
