Bear in mind that there is a considerable difference between the size of a hydrogen atom and a uranium atom. Atoms are not all the same size. But in general they are in the one to five angstrom range (an angstrom being a tenth of a nanometer; a nanometer being a billionth (10^-9) of a meter).

∙ 15y agoThere is no average diameter of an atom per se because each atom varies in size due to the number of electrons in its shell, as well as which shell is its valence cell. There is an average diameter of an atom given which shell its valence shell is, however, and that is about 1 x 10^-10 meter. On an accurate scale, imagine a football stadium with a ball in the centre lines and peas on the furthest seats in the stand. The peas are electrons and the ball is the nucleus.

∙ 13y agoThe smallest and lightest nucleus, that of hydrogen, has a diameter of about 1.75 quadrillionths of a meter. The nucleus of a heavy atom such as uranium has a diameter of about 15 quadrillionths of a meter. To express a meaningful average, we would have to know which collection of atoms you have in mind: the human body? the earth's crust? the entire earth? the entire solar system? the entire Milky Way galaxy? Generally there will be many more lighter atoms than heavier ones, so in many cases the average will be closer to the lower end of the range of 1.75 to 15 quadrillionths of a meter.

Note: 10-10 m is 1 Angstrom.

What is the diameter of nucleus?
The diameter (not the volume of diameter) of the atomic nucleus is between 1,75.10-15 m and 15.10-15 m, depending on the chemical element.If you want the volume and if the nucleus is a perfect sphere: V=Î?d3/6.
How many electrons surround the nucleus of an atom of aluminum?
14 neutrons because the average atomic mass is about 27 and there are 13 protons.
WHAT IS THE AVERAGE DIAMETER of A copper atom?
hey ive found this site. it helped me a lot. the diameter of copper is 2.551 x 10^-10 m http://www.copper.org/resources/properties/atomic/homepage.html
Most of the mass of an atomic concentrated in the what?
Nucleus.
The particle that moves around the nucleus is?
Electrons move around the atomic nucleus.
Is atomic mass and atomic diameter the same thing?
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
Diameter of the center of the atom of hydrogen?
The atomic nucleus of hydrogen atom has a diameter of 1,75 femtometres.
An atomic neucleus has a diameter of aproxamiately?
Depends a carbon nucleus is 40 times the size of an hydrogen nucleus.
How many times greater is the diameter of an atom than the diameter of its nucleus?
Well it is not a fixed ratio, each element has its own diameter for the atom and nucleus depending on atomic number and atomic weight. but an idea can be given: for a certain elemnt the atom daimeter is 225 picometer and the nucleus diameter is 6 femtometer ,the ratio would be ( 225x 10^ - 12) /(6x 10^ - 15)= 37500.
What is the diameter of nucleus?
The diameter (not the volume of diameter) of the atomic nucleus is between 1,75.10-15 m and 15.10-15 m, depending on the chemical element.If you want the volume and if the nucleus is a perfect sphere: V=Î?d3/6.
What does the atomic mass tell you?
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
What is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
How many nuclei would have to be placed to fit the diametre of an atom?
The average nucleic diameter is about 9 fm (9 x 10^-15). The average atomic diameter is about .3 nm (.3 x 10^-9). Finding the volume of the atom and nucleus (as spheres), and dividing the former by the latter yields 3.7 x 10^13. 37,000,000,000,000 (37 trillion) average sized nuclei can fit in the diameter of an average sized atom.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
What is smaller electron or nucleus?
Atomic nuclei are much-much smaller than cell nuclei.Why? Because a cell nucleus contains an enormous number of molecules, each molecule built from a number of atoms, with every single atom containing a tiny little (atomic) nucleus. For instance, an oxygen atom (which is a common component of living cells - think about water, H2O) is about 20 thousand times larger in diameter than its (atomic) nucleus.Actually, if you magnified a typical cell nucleus (6 μm of diameter for average mammalian cells) to the size of the Earth (diameter of Earth: 12756.2 km), then the oxygen's atomic nucleus (actual diameter: 5.4 fm) would look like a half-inch (12.8 mm) ball at the same magnification.That means that - as far as size is concerned - the atomic nucleus compares to the cell nucleus as a blueberry (or a smaller hazelnut) compares to our planet.
What the atomic number of nucleus of atom?
what is the atomic number of the nucleus?
Where is the most of the volume of an atom found at?
If we are talking about an atomic nucleus, it very much depends on which element in the periodic table. However, the volume of an atomic nucleus is so very small compared to the volume of the entire atom that it is next to nothing and the actual numbers are rather meaningless. An atomic nucleus has a diameter of somewhere around 1 to 10 femtometres (ten to the power minus 15 metres) and if considered as a sphere, the volume would be calculated using the formula 4/3 times pi times (half the diameter) cubed. Mind-bogglingly small.
