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.

University of Queensland scientists have cracked a long-standing puzzle in nuclear physics, showing that nuclear polarization ...

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 ...

The study revealed how the structure of a nucleus relates to the force that holds it together. This understanding could advance efforts in quantum physics and across a variety of sectors ...

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 ...

Researchers have combined theory and experiments to show that nuclear polarization does not limit studies of muonic atoms, clearing the way for new nuclear physics experiments.

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 ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles ... single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane ...

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 ...

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 ...
