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.
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 ...
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 ...

CERN’s strong evidence points to ‘heaviest doubly magic nucleus’ of tin-100Researchers at CERN have made a significant breakthrough in nuclear physics by uncovering strong evidence that Tin-100 (100 ...
Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...
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 ...
