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.

Advancements in structural nanomedicine aim to standardize nanomedicine formulations, improving treatment consistency and ...

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 ...

A brilliant flash from deep space once baffled scientists. But now, that mystery has been solved—and it reshapes what we know ...

to 47 (silver), without getting all the way up to the heaviest elements such as gold (atomic number 79) or actinides like thorium (90) and uranium (92). This weak r-process could occur in a variety of ...

Atoms come together in hopes of becoming more stable, thus making some of the most essential compounds we know today – carbon dioxide, water, salt, and acids. Atomic elements are arranged on the ...
