The number of protons is what defines the element, i.e. an atom with six protons in its nucleus will always be carbon, and uranium will always have 92 protons. The total number of particles in the ...

This is a network that provides support to the whole nucleus. It is made up of intermediate V type filaments composed of lamin proteins. It forms an elastic structure near the nuclear periphery ...

Electronic structure can be shown as a list of numbers or as a diagram. Take lithium for example. The diagram above shows each shell as a circle around the nucleus, with each of the three ...

Findings in nuclear physics theory have received several Nobel Prizes (1975-nucleus vibrations and rotations, 1963-nuclear shell model, 1949-meson exchange model of nuclear forces). Despite these ...

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 ...

Researchers unveil the fractal globule structure of DNA, providing new insights into genome organization and its implications ...

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 ...

From the evidence of karyomeres in animal cells, the nucleus is regarded as a compound structure, and it was further suggested that the spindle is also compound, the real unit in mitosis being a ...

The electrons in an atom tend to occupy distinct shells. What about particles in the nucleus? The "magic numbers" of the isotope chart suggest that they also have a shell arrangement ...
