The smallest unit for measuring distance is the attometer. The attometer is equal to one 1,000,000,000,000,000,000th of a meter. This is the only unit small enough to provide some degree of precision when measuring distances on the atomic level - like the diameter of an atom's electron cloud.
What else can I help you with?
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
These whiz around the outside of atoms?
The electron cloud.
Which is more massive an atoms nucleus or an atoms electron cloud?
The nucleus, consisting of protons and neutrons, is much more massive than the electrons.
Who developed the electron-cloud model?
The electron cloud theory was developed in the late 1930s and early 1940s.
What is an electron cloud shaped liked?
The shape of an electron cloud depends on the energy sublevel. Each electron cloud is different, so there is no definitive shape.
What unit is used to measure the diameter of the electron cloud?
Fermi
What unit is used to measure the diameter of an electron cloud?
fermi
What is the name of an atoms outer region?
electron cloud
What is radii in chemistry?
In chemistry, radii refer to the measurements of the size of atoms. It is commonly used to measure the distance from the nucleus of an atom to its outer electron cloud. Radii are important in understanding the reactivity and bonding of atoms in chemical reactions.
What is the atoms electron cloud?
The distribution of electron around an atom in various shells is sometimes referred to as electron cloud. If there are more electrons in certain space around the atom, that space is said to have a denser electron cloud.
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
What shield prevents other atoms from moving into another atoms space?
The electron cloud.
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.
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.
What is the Diameter of a helium atom in meters?
The diameter of a helium atom is approximately 0.1 nanometers, or 1 angstrom. In meters, this translates to about 1 × 10^-10 meters. Helium atoms are among the smallest atoms, with their size largely determined by the electron cloud surrounding the nucleus.
Where is a electron?
In atoms. More specifically, they orbit the nucleus of an atom, in the aptly name electron cloud. Or electron shell.
These whiz around the outside of atoms?
The electron cloud.
