The atom that is smallest in size is the hydrogen atom.
By the size of the atom and its mass
An atom is the size of an orange compared to the Earth.
The size of a silicon atom is about 0.11 nanometers.
The atom itself would be the size of an NFL stadium.
No. It is the only way to measure an atom because the orbital is the outer part of the atom and determines its size.
The physical size of an atom is largely determined by the size of the electron cloud.
The electrons are repelled by the protons, which causes then to be farther away. If the nucleus was the size of a marble, then the atom would be the size of a football stadium. Correction: Electrons are not repelled by the protons but are attracted to them. Opposite charges attract.
The size of an atom refers to the typical distance from the nucleus to the boundary of the surrounding cloud of electrons.
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
The smallest atom is hydrogen.
