Is the density of the nucleus higher than that that of the whole atom?

Answer 1

The nucleus of an atom has a phenomenally high density! Consider the nucleus of Hydrogen, (a proton). This has a mass of approximately 1.67 x 10-27kg, and the radius of this nucleus is approximately 10-15 m. Therefore, on the assumption that the nucleus is spherical, the volume of the nucleus is given by the volume of a sphere; Volume = (4/3)(PI)r3 , Mass = 1.67 x 10-27 kg, Density = Mass/Volume Therefore Density = [1.67 x 10-27 kg]/[(4/3)(PI)r3] substituting in; PI = 3.1416, r = 10-15 m This yields; Density = 4 x 1017 kg m-3 !!!! This is almost equal to a million million million kg m-3 or a thousand million million tonnes m-3 !!!!

Answer 2

You practically answered your own question. It's not called an electron "cloud" for nothing. There is so much space in that cloud that it took many scientists many years (and lots of math) to realize that it even existed. Nuclei are much, much denser.

Answer 3

Since Density= Mass/volume.

Hence, higher the mass of the nucleus, higher is the density.

So elements which have more protons and neutrons in their nucleus, have more density than others.

Answer 4

The nucleus is very dense. If the nucleus of an atom were the size of the dot in an exclamation point, its mass would be approximately as much as that of 70 automobiles.

Answer 5

Yes because the atom as a whole would have electron clouds and electron clouds have an almost unmeasurable density where as the only dense part to the atom is the nucleus.

Answer 6

Yes it has a high density

No it is not negatively charged (it is positively charged) - (UNLESS it is an atom of antimatter).

Answer 7

it has a low density

Answer 8

Yes, it is true.

Answer 9

Yes
