How many times larger is the radius of the electron cloud than the radius of the nucleus?
100,000 times
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.
When the electron cloud is not distributed symmetrically a molecule has a what?
Polarity
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.
What is the shape of an atom?
It is generally envisioned that the atom consisting of a dense, small nuclues is made up of spherical protons and neutrons, yet this nucleus is surrounded by electrons constantly in rapid motion, orbiting the nucleus so frequently that it often covers a larger sphere around it. However, since the electrons are constantly moving, they hold no actual shape, so we call this area in which the electron orbits the nucleus the Electron Cloud. For modeling purposes, an atom is often displayed as a simple sphere with no complexions, but no one knows for sure exactly what these atoms look like upclose.
How does the mass of the nucleus compare to the mass of the electron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
How many times larger is the radius of the electron cloud than the radius of the nucleus?
100,000 times
How does it's atomic radius compare to that of krypton?
The element krypton's atomic radius is 189 pm. This is a measurement of its atom sizes or the distance between the electron cloud and the nucleus.
What is a region in an atom where there is a high probability of finding electrons?
The electron cloud. The atomic radius roughly describes the distance from the nucleus to the electron cloud.
Where are the nucleus and electron cloud?
nucleus is in the middle and the electron cloud is around it
How does the size of the nucleus of an atom compare to the size of the electron cloud?
I need to know also
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...
How can you use atom electron nucleus and electron cloud in the same sentence?
The atom's nucleus contains protons and neutrons, while electrons are found in the electron cloud surrounding the nucleus.
Where is a electron cloud located?
The electron cloud in an atom is located outside of the nucleus.
How are an atoms nucleus and its electron cloud different?
The nucleus of an atom contains protons and neutrons, while the electron cloud surrounds the nucleus and contains the electrons. The nucleus is positively charged and is much smaller in size compared to the electron cloud. The electron cloud determines the size of the atom and contains most of the atom's volume.
The radius of an atom extends to the outer edge of the what?
The radius of an atom extends to the outer edge of its electron cloud, which is the region where electrons are most likely to be found in. The electron cloud represents the volume of space where electrons can exist around the nucleus of an atom.
