BEIJING -- Chinese researchers have synthesized two new nucleus isotopes that contain 84 neutrons and 82 neutrons, according to a recent research article published in the journal Physical Review ...

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have ...

The different types of chlorine are called isotopes of chlorine ... 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 relative charge of a nucleus is the same as its proton (atomic) number. Key fact: isotopes are forms of an element that have the same number of protons but different numbers of neutrons.

"Our method can achieve higher precision for isotopes that have been challenging ... of the re-determined mass values for the reference nuclides with (a) and without (b) the new technology.
