Electrons are considered point particles in the Standard Model of particle physics, meaning they do not have a physical size or radius in the classical sense. However, for theoretical purposes, some models suggest an effective "radius" of about (10^{-18}) meters, but this is not a definitive measurement like that of a macroscopic object. Instead, electrons are better described by their properties, such as charge and mass, rather than a physical size.

How many times larger is the radius of the electron cloud than the radius of the nucleus?

What electron has the largest radius?
The electron itself does not have a well-defined "radius" in the same way that classical particles do, as it is considered a point particle in quantum mechanics with no spatial extent. However, in the context of atomic orbitals, the electron in the outermost shell of an atom, such as those in larger atoms like cesium or francium, can be considered to have the largest effective radius due to its greater distance from the nucleus. In this sense, outer electrons in these heavy alkali metals exhibit the largest average distance from the nucleus compared to electrons in smaller atoms.
What is the distance with the highest probability of finding a dot in the probable location of ean electron?
The highest probability of finding an electron is typically at a distance corresponding to the electron's most likely radial position within an atom's electron cloud. In the case of hydrogen, for example, this distance is often described by the Bohr model, which indicates that the most probable distance for the electron is at the Bohr radius, approximately 0.529 angstroms (or 5.29 x 10^-11 meters) from the nucleus. However, this can vary based on the specific atom and the electron's energy level.
Is radius half radius?
No. Radius is half of the diameter.
What happens to the atomic radius when an electron is gained?
The negative ionic radius is larger than the neutral atomic radius
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
What happens to atomic radius when electron is lost?
When an atom loses an electron, it typically becomes a positively charged ion (cation). This loss of an electron results in a reduction of electron-electron repulsion in the electron cloud, which allows the remaining electrons to be drawn closer to the nucleus. As a consequence, the atomic radius decreases. Thus, the atomic radius of an atom decreases when it loses an electron.
When the atom becomes an anion what happens to its radius?
The radius of an anion is bigger than the radius of a neutral atom.
What is the radius of the electron's spiral path?
The radius of the electron's spiral path is determined by its energy and the strength of the magnetic field it is moving through.
What happens to ionic radius if you add an electron?
Adding an electron to an atom increases its negative charge, leading to an increase in electron-electron repulsions. This results in the outer electron shell expanding, causing the ionic radius to increase.
How does the radius of the electron cloud compare to the radius of the nucleus?
It is about 100,000 times larger
What is the ratio r proton /r electron of the radii of their circular paths?
The ratio between radius of proton to the radius of electron is just 0.3
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
How does the ionic radius of a typical anion compare with radius for corresponding neutral atom?
The ionic radius of a typical anion is larger than the radius of the corresponding neutral atom. This is because when an atom gains an electron to become an anion, the extra electron increases the electron-electron repulsion, causing the electron cloud to expand, resulting in a larger ionic radius.
How many times larger is the radius of the electron cloud than the radius of the nucleus?
100,000 times
