Why do excited atombs absorb and reemit radiation at characteristic frequencies?
Excited atoms absorb and reemit radiation at characteristic frequencies because the electrons in the atom can only occupy specific energy levels. When an atom absorbs energy and its electrons are excited to higher energy levels, they will subsequently drop back to their original energy levels by emitting photons with specific frequencies that are unique to that atom. This results in the emission of radiation at characteristic frequencies.
Each element has its own set of characteristic absorption lines because?
each element has a unique arrangement of electrons in its atomic structure. When these electrons absorb energy, they move to higher energy levels and then emit light as they return to their original state. This emitted light results in characteristic absorption lines that are specific to each element.
Why do different metals exhibit unique flame test colors?
Different metals exhibit unique flame test colors because when they are heated in a flame, the electrons in their atoms become excited and jump to higher energy levels. When these electrons return to their original energy levels, they emit light of specific wavelengths, which correspond to different colors. Each metal has a unique arrangement of electrons in its atoms, leading to distinct flame test colors.
How are discrete wavelengths of light emitted by an excited gas?
The gas is excited by electricity which moves electrons to a higher orbit in the inert gases atoms. When they fall back to where they were they give off a photon. That color is unique to that atom. The spectrograph of an element is unique to that atom alone. This is how we can tell what stars are made of.
In what sense is a black hole actually black and how does this characteristic contribute to its unique properties and behavior?
A black hole is black because its gravity is so strong that not even light can escape from it. This characteristic contributes to its unique properties and behavior by causing it to have a powerful gravitational pull that can distort space and time, and also by allowing it to absorb matter and energy without emitting any light or other forms of radiation.
What is it called this unique characteristic of copper?
The unique property is that it contains 29 protons and, in its neutral state, 29 electrons.
Which is a unique characteristic of the bonding between metal atoms?
A unique characteristic of the bonding between metal atoms is metallic bonding, where the metal atoms share their electrons freely throughout the entire structure. This results in a "sea of delocalized electrons" that are free to move, giving metals their unique properties such as malleability, ductility, and high electrical and thermal conductivity.
Why do metals always impart their characteristic colors to a flame?
The defining characteristic of metals, in a chemical sense, is that they have between one and three valance electrons and they tend to lose electrons, as compared to non metals which have a larger number of valance electrons and are much less prone to losing them. So, when a metal is heated sufficiently, outer electrons get hot enough to leave the atom. Then, electrons are recaptured. In the process of becoming part of an atom again, an electron emits a photon, with a typical wavelength for a given element, thereby creating a characteristic color. As a result of this process, the color of a flame is mainly due to whatever metals are present.
What is a specific characterstics?
A specific characteristic is a unique quality or feature that distinguishes one thing from another. It is a defining trait that helps to identify or describe an object, person, or animal.
What is a unique characteristic of a rabbit?
the unique characteristic of a rabbit was jumping, eating carrots...........
Which number associated with an atom is a characteristic property?
Atomic number is a characteristic property of an atom. Each element has its own unique atomic number, which is the number of protons in the nucleus of an atom.
What if the following is characteristic of a metallic bond?
In a metallic bond, atoms share their electrons freely, allowing them to move throughout the structure and creating a "sea of electrons." This shared electron cloud gives metals their unique properties such as high electrical and thermal conductivity, malleability, and ductility. The presence of delocalized electrons is a key characteristic of metallic bonding.
What are characteristic's of sediment?
there unique:)
What is a characteristic property of an element?
A characteristic property of an element is its atomic number, which determines the element's identity on the periodic table. Each element has a unique number of protons in its nucleus, which is constant for that element regardless of its chemical state or conditions.
What is a prominent or distinguishing aspect of something?
A prominent or distinguishing aspect of something is a key characteristic or feature that sets it apart from others in a noticeable way. It is usually a defining quality that makes that thing unique or easily recognizable.
One unique characteristic about the sun?
One unique characteristic about the sun is its color. Another is the way it put off heat.
What is a characteristic of an element?
One characteristic property of an element is the number of electrons it has.
