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.

An element's atomic number defines it. An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons ...

By measuring this from all angles at the same time, the scientists were able to create spatial maps of the cell nucleus that reveal how its mechanical structure changes over time. They found that ...

The results of the described studies open up new perspectives for a better understanding of the structure of the atomic ...

Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...

The former, however, explains RNA-world relics and linear chromosomes in eukaryotes, is consistent with Horiike and colleagues' results 1 and argues against an archaeal origin for the nucleus.

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were ...

The atomic nucleus is a quantum many-body system composed of protons and neutrons, typically exhibiting a size similar to that of neighboring nuclei. A halo is an exotic nuclear structure found in ...
