What is the average size of atom?

The average size of an atom is around 100 picometers (10^-12 meters). This size can vary depending on the specific element and its atomic number.


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.


Which atom is the smallest in size?

The atom that is smallest in size is the hydrogen atom.


What is the size of an atomic nucleus?

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.


The volume of an atom is determined by the size of?

By the size of the atom and its mass


Emilio wants to build a scale model of an atom that is one million times the size of an average-size atom. About how big will Emilio and model be?

An atoms has a diameter of about 1x10^-10 meters to about 5x10^-10 meters. Using the larger number, and making it 1 million times bigger, you would have something with a diameter of5x10^-10 meters x 1x10^6 = 5x10^-4 meters, or put another way, the diameter would be about 0.5 mm


The size of an atom nucleus or cell?

An atom nucleus is typically on the order of femtometers (10^-15 meters) in size. A cell is much larger, with most human cells ranging from 10 to 30 micrometers in diameter.


If the electron in a hydrogen atom were the size and weight of a golf ball what would be the size and weight of the proton and neutron and what would be the orbital diameters of the electron and neutr?

If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).


What is the approximate size of an atom?

An atom is the size of an orange compared to the Earth.


What is the size of a silicon atom?

The size of a silicon atom is about 0.11 nanometers.


If the nucleus of an atom were the size of a marble then the atom itself would be the size of?

The atom itself would be the size of an NFL stadium.


Is measuring the size of an atom by the size of its orbital not very accurate?

No. It is the only way to measure an atom because the orbital is the outer part of the atom and determines its size.
