Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.
The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...
After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all its mass, and positive charge, in a central nucleus about 10,000 times smaller than ...
The IAEA's NUCLEUS information resource portal provides access to over 100 scientific, technical and regulatory resources, including databases, applications, publications and training material. As it ...
Another protein, Aly/REF, also binds mRNA in the nucleus, but does not co-immunoprecipitate with mRNA in the cytoplasm. This indicates that at some stage before, during or after nuclear export ...

In a surprising turn of events, an international team of scientists has found that lead-208 (208 Pb), the heaviest known "doubly magic" nucleus, exhibits unexpected shape characteristics that ...
In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding that the proton did not seem to be the only ...
