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 secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, ...

CERN researchers found that atomic nuclei shapes impact high-energy collision outcomes, offering new insights into nuclear ...

The central dogma of biology defines the flow of genetic information: It describes how proteins are made from mRNA templates, ...

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 ...

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 ...

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 ...

In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and ...

Beyond the ladder-like structure described above ... thereby compacting it enough to fit inside the nucleus (Figure 8). Together, eukaryotic DNA and the histone proteins that hold it together ...
