How big the nucleus is compared to an electron?

Answer 1

That depends on your definition of 'nucleus'. The nucleus or core of an atom is, obviously, smaller than the atom as a whole. But seeing as you placed this question in Biology, a cellular nucleus is many billions of times the size of an atom.

Answer 2

We know that the nucleus of an atom contains the nucleons, the protons and neutrons that make up that atom. This is almost all the mass of the atom, and these protons and neutrons are bound very tightly. That translates into the fact that the nucleus takes up almost none of the volume that the atom as a whole occupies. The orbiting electrons that are in the electron cloud actually define the volume of the atom. And that atom's volume is really large compared to that of the nucleus. We might say that the nucleus contains almost all of the mass of the atom, and takes up almost none of its volume. The difference between the size of the atomic nucleus and the size of the whole atom is that dramatic.

Answer 3

We have two examples: the first is, if the Atom is the size of a New York Baseball stadium, then the nucleus is the size of a flea perched on the pitcher's mound; and next, if the atom is one mile [1.6 km] across the atomic nucleus would be two-thirds of an inch [< 2 cm] in diameter. From this we can state that the Atom is 99.9999 % empty space.

Answer 4

The nucleus of an atom consists of protons and neutrons. Electrons Orbit the nucleus. Protons and neutrons are approximately the same mass and about 1875 X the mass of an electron.

Size wise nuclei range from 15 fm to 75 fm (fm is a femtometre, 10-15 metres) Electrons are 2 fm (classical approximation) although bearing in mind quantum mechanics and heisenbergs principle this is perhaps less meaningful than the size of the nucleus., the Compton wavelength of the electron is 2.4 X10-12 m about 2400 fm.

Answer 5

Incredibly small. About 1/10000 the diameter.
