Can you determine the exact location of an electron in an atom?
No, it is not possible to determine the exact location of an electron in an atom. Instead you can only calculate the electron's probable location within the atom.
There is no exact location of the electron. The electron is outside the nucleus orbiting the center of the atom. You can't see it because it rotates so fast and is so small. So we can't indicate the exact location of the electron.
You just said it, electrons. The "shell" is just an energy level. It is called a shell because it surrounds the atom, but it is just the electrons. Since there is no way to determine the exact location of an electron, it is referred to as an "electron cloud."
because electron has dual nature.it acts as a wave & also as a particle. the exact path of a wave cannot be determined.only probability of electron can be given
Electrons orbit the nucleus of an atom. The exact location of a specific electron, however, can not be known for certain. The general area where the electron might be found is in its orbital.
There is no way to measure the exact location and path of an electron.
Do scientists use the electron cloud model to describe the exact location of electrons around the nucleus?
Scientists do not use the electron cloud model to describe the exact location of electrons around a nucleus. Electrons are quantum particles that exist as points and waves. As a wave, it cannot be said that an electron occupies any exact location, rather, the probability of its charge's existence is spread out in a cloud surrounding the atom.
valence electron determine the group of an atom and hence its chemical properties
The location of an electron is circling the outside of an atom.
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
One of the first things one must understand about our Universe -- and experiments have found this aspect of quantum mechanics to be true -- is that you can NOT determine the location of an electron within an atom. All you can do is determine the probability that an electron will, over time, be at a specified place. It is NOT the case that we lack the instrumentation or the cleverness to measure this, it… Read More
It is located on the outer layer of an atom.
It is due to the Heisenberg Uncertainty Principle, where one cannot know both the position and velocity of a particle. If you know that there is a high probability of finding a particle in one particular region, then you will have less certainty of the particle's position. Because all particles in an atom are in constant motion, you will not know with certainty where a particle is.
How does the location of the electron differ in Bohr's atomic model and the quantum mechanical model?
In Bohr's model the atom was described as a 2 dimensional structure quite like the solar system which it is not. The rings are not rings but spheres or dumbles. The exact location of the electrons cannot be found out and thus it is considered as a cloud of electron that revolve around the nucleus of an atom.
by the butt of it
The electron can either be by itself outside of an atom, or can be in an atom in a series of energy 'shells' outside of the nucleus.
The electron. The electron is has a negative charge. The more electrons that are in a valence shell of the atom the more negative the atom will be.
In the nucleus, and orbits it.
The electron holds the negative charge of an atom. In the standard model the electron(s) form a 'cloud' around the nucleus of the atom.
I believe the "electron cloud" I have a BS in chemistry =P
How do the energy and the most probable location of an electron in the third shell of an atom compare to the energy and the most probable location of an electron in the first shell of the same atom?
in the third shell, an electron has more energy and is further from the nucleus
In the shells around the nucleus
It is difficult to determine the percentage of isotopes.
The Quantum Mechanical model of the atom states that the location of the electrons around the atom cannot be precisely determined. The region where the electron can probably be found is known as the electron cloud.
According to quantum theory, we can never know the exact location of an electron at any given time. If the electron is part of an atom, the best we can do is state the probability that the electron can be found within a given region about the nucleus. Often that information is good enough for our purposes.
The bohr model is an innaccurate model of the atom because there is no way to measure the exact of an electron in an atom?
It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
I can be determined precisely
This branches into quantum physics. In Quantum physics an electron orbit is more of a probability of locating an electron at a given point in space than any implied motion of said electron. This and the discreet nature of energy in the quantum world means that there is no where lower for the electron to go once it is in the ground state. Therefore if it collapsed we would be able to determine it's exact… Read More
An uncertainty theory used with the modern electron cloud model of the atom that says it is impossible to determine an electron's exact position and speed as it moves around?
Werner Heisenberg proposed in 1927 the uncertainty principle.
Outer, or valence, shell electrons do.
The atomic number represent the number of protons in an atom. Protons have a positive charge, which means they will attract electrons, which have a negative charge. The amount of protons in an atom will determine the number of electron it has. The more the protons, the more the electron it can hold. The number of electrons, in turn, will determine how the atom interact with other atoms. For example, hydrogen atoms have 1 proton… Read More
Electrons can never have a determined location. They are present in a zone called the electron cloud.
An atom has a nucleus at it's center, where the protons live. The electrons zoom around it.
The more electrons in a atom, the bigger it's electron cloud, therefore making the atom bigger
In a shell at a distance form the atomic nucleus. The Electron Cloud
It is used to determine the electron configuration of an atom, molecule or ion.
a neutron's location in an atom is in the core, or nucleus, of that atom, this nucleus is made of both neutrons and protons. the electrons of an atom are located in the electron cloud that surrounds the nucleus. to picture this, imagine a baseball field. the pitchers mat is the nucleus, and all the remaining area of the field, including the bleachers, is the electron cloud.
An electron's exact position cannot be pinpointed.
The energy required to remove completely an electron from its atom.
The charge on an electron is negative (it's -1), and electrons in an atom are found in orbitals (or Fermi energy levels) in the electron cloud far from the nucleus.
Hydrogen, when trying to determine the number of electrons there are in a atom reference the atomic number. In this case Hydrogen is number 1 so hydrogen has 1 electron.
Yes, it is true.
I think it's an orbital...
An electron in the outermost energy level of an atom is called a valence electron. (We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.) These electrons determine the chemical reactivity of the atom. the valence electrons
What are the principal factors which determine the ease with which a given electron may be removed from an atom?
In 1926, austrian physicist erwin schrodinger wondered why electrons had to be limited to specific orbitals as proposed by neils bohr. He proposed a new model in which electron move in cloudlike orbits rather than fixed ones. He said it is impossible to know the exact location of electrons. The best we can do is know where the electron probably is. Physicists still use the quantum model of the atom today.
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
the most probable location of an electron
Electron density is the measure of the probability of an electron being present at a specific location. In molecules, regions of electron density are usually found around the atom, and its bonds.
How do you determine the type of hybridization of the central atom by relating it to the molecular geometry?
check valence electron
No. Quantum Theory states that we can only know the probable location of an electron. Electron Orbitals are just the three dimensional representations of the most likely location of the electron. Electron movement is not well understood and highly unpredictable.
