Can you explain why the estimation of the diameter of an atom is greater or less than the known value?
Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
How does the radius of the electron cloud compare to the radius of the nucleus?
It is about 100,000 times larger
Why does the electron cloud have a very small mass?
The electron cloud has such a small mass because that's where all the electrons are! Electrons are fundamental particles having a mass of only 9.109 X 10-31 kg. To put that into perspective, a proton has a mass of over 1,800 times that of the electron.
How many times larger is the radius of the electron cloud than the radius of the nucleus?
100,000 times
Does lighting come from the ground?
There are 3 main places lightening can travel from. The ground to a cloud, a cloud to a cloud, and the cloud to the ground.
When the electron cloud of a molecule is easily distorted the molecule has a high?
Polarizability
Define Polarizability What is polarizability?
It is a measure of how easily an electron cloud is distorted by an electric field. Electron cloud will belong to atom, molecule or Ion. It is the quantitative measurement of the extent to which the electronic cloud can be polarized
Who developed the electron-cloud model?
The electron-cloud model was developed by Sir George Paget Thomson in 1924. He proposed that electrons in atoms are distributed like a cloud around the nucleus, rather than in specific orbits.
What is a electron cloud?
An electron cloud is an atomic orbital.
Is the electron found in the electron cloud or in the nucleus?
Cloud...
Is the electron found in the electron cloud or the nucleus?
Cloud...
Why is dipole moment never permanent?
Electrons are constantly moving around the molecule. The dipole moment is just an average or where the electron cloud most likely to be if you were to freeze the molecule.
What is a detailed explanation of the electron cloud model?
Scientist use the electron cloud model to represent an atom.In the electron cloud model, an atom has two distinct regions-the nucleus and the electron cloud.
Where are the nucleus and electron cloud?
nucleus is in the middle and the electron cloud is around it
What is found in the electron cloud of an atom?
The electron cloud of an atom contains the electrons, which are negatively charged particles that orbit the nucleus in different energy levels or shells. The electron cloud represents the probability of finding an electron at a particular location around the nucleus.
How do you draw an electron cloud model?
How do you draw and electron cloud for 2Br and for Br2
Where is a electron cloud located?
The electron cloud in an atom is located outside of the nucleus.
