The size of an atomic nucleus is typically on the order of femtometers (10^-15 meters), which is much smaller than the size of the atom itself. The nucleus contains protons and neutrons tightly packed together in a small volume at the center of the atom.

How is knowledge about the size of the atomic nucleus is based on probability?

The size of a nucleus may be measured by firing sub-atomic particles at the nucleus and counting the proportion that bounce off the nucleus rather than miss it entirely. Assuming that the nucleus is spherical in shape, the ratio allows its size to be estimated.


Which scientist deduced the size of the atomic nucleus?

Rutherford


What is the Atomic size of oxygen?

The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.

What is the atomic number of the nucleus?

The atomic number is the number of protons in a nucleus.


What is the size order for these scientific particles Proton Neutron Atom Electron Nucleus?

IIRC Atoms (contains Protons/Neutrons and electrons) Nucleus contains Protons and Nuetrons Proton atomic size 1 Nuetron atomic size 1 electron atomic size 1/1836 i.e the proton is 1836 bigger than the electron


Why does atomic size increase as you go from left to right across a period?

Atomic size decreases from left to right across a period because the effective nuclear charge increases due to more protons in the nucleus, pulling the electrons closer. This results in stronger attraction between the nucleus and the electrons, leading to a decrease in atomic size.


What describes the size of an atom?

The size of an atom is typically described based on its atomic radius, which is the distance from the nucleus to the outermost electrons. Atomic radius can vary depending on the element and its electronic configuration.


How does the size of an atomic nucleus compare with the size of the whole atom?

Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).


Atomic number in the atomic nucleus?

The atomic number is equal to the number of the protons in the atomic nucleus.


Define atomic radii?

The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.


What does atomic radius means?

Atomic Radius means the size of the atoms, the distance from the atomic nucleus to the outermost electron orbital.
