The diameter of the helium-4 nucleus is about 1x10-15 m.
The diameter of the nucleus of Encke's Comet is 4.8 km
The diameter of a typical nucleus is only about 1 × 10-14 m (4 × 10-13 in), or about 1/100,000 of the diameter of the entire atom.
The nucleus is one the order of one fermion in diameter. The nearest electron orbital is on the order of more than a thousand fermions from the nucleus. To me, that pretty far away.
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
Approx. 15 femtometers (1 fm = 10-15 m)
0.00625mm
what kind of atom there not all the same(1.75×10−15 m)this is the diameter of a hydrogen nucleus
The diameter of the nucleus of Encke's Comet is 4.8 km
100,000 times.
it's ovisly 97%
The atomic nucleus of hydrogen atom has a diameter of 1,75 femtometres.
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
Depends a carbon nucleus is 40 times the size of an hydrogen nucleus.
1,75.10-6 nm
Protons and neutrons make up the nucleus in an atom, the electrons are in shells or orbits around that nucleus at quite a distance (relatively to the nucleus diameter)
The diameter of a typical nucleus is only about 1 × 10-14 m (4 × 10-13 in), or about 1/100,000 of the diameter of the entire atom.
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.
