Isotopes are atoms of the same element with the same atomic number but different mass numbers due to a difference in the number of neutrons. Some atoms exist in nature as a mixture of isotopes.

A is the mass number (the sum of the protons and neutrons) Z is the atomic number (the number of protons) X is the chemical symbol of the element Note: the number of neutrons in the nucleus can be ...

Neutrinos and antineutrinos are elementary particles with small but unknown mass. High-precision atomic mass measurements have revealed that beta decay of the silver-110 isomer has a strong potential ...

In the quest to generate limitless clean energy, China has just taken a step closer. Scientists have achieved the milestone ...
