An atom is the size of an orange compared to the Earth.
The approximate size of a sodium atom is about 0.186 nanometers (nm) in radius. Sodium is a relatively large atom compared to hydrogen or helium because it has more electrons and protons, leading to a larger atomic radius.
An atom is typically around 0.1 to 0.5 nanometers in diameter, which is equivalent to about 1 to 5 angstroms. This size can vary based on the type of atom and its electron cloud. The nucleus, which contains protons and neutrons, is much smaller, on the order of femtometers (10^-15 meters). Overall, the vast majority of an atom's size comes from the space occupied by its electrons.
The approximate mass of an atom that contains 10 protons and 11 neutrons is 21.
The atom that is smallest in size is the hydrogen atom.
Nucleus of a cell ~10-7 - 10-6 m Atomic nucleus ~10-14 m
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.
By the size of the atom and its mass
The size is 100
The size of a silicon atom is about 0.11 nanometers.
The heart is about the size of the person's fist.
Yeah
The atom itself would be the size of an NFL stadium.
