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.

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 ...

University of Queensland researchers have made a breakthrough in muonic atom research, clearing the way for new nuclear ...

For decades, scientists believed that lead-208, a "doubly magic" and highly stable atomic nucleus, was perfectly spherical.

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 ...

The film explores the structure and function of plant and animal cells using a microscope. It begins with observing onion cells, highlighting their components such as the cell wall, nucleus, and ...

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 ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

The discovery challenges fundamental assumptions about nuclear structure and has far-reaching ... stable due to being a "doubly magic" nucleus—and is the heaviest that we know of.

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 ...
