In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei.

In the final weeks, oxygen atoms fuse into silicon (atomic number 14), phosphorus (atomic number 15), and sulfur (atomic number 16).

Atomic Number and Atomic Mass: Get here the easy notes on atomic number and atomic mass for all the first 30 elements. Know how to calculate atomic mass using atomic number.

The world’s largest atom smasher has conducted its first-ever collisions between protons and oxygen ions, as part of an ...

Discover the history, structure, and importance of the periodic table of elements, from Mendeleev’s discovery to modern scientific applications.

Atomic number and mass number Oxygen and carbon are both elements. Both are made up of atoms which in turn are made up of protons, neutrons and electrons. But what makes oxygen different from carbon?

Atomic images reveal unusually many neighbors for some oxygen atoms Date: October 21, 2019 Source: University of Vienna Summary: The identification of new chemical bonds is crucial for the design ...

Unlike molecular oxygen, or O2, made of oxygen atom pairs, atomic oxygen is composed of individual oxygen atoms. Venus' crust is surprisingly thin. Could this explain why it's so geologically active?
