Determining the structure of a molecule, atom by atom, is important for both chemists and biologists to understand how molecules work and interact with surrounding material.

Aluminum oxide (Al2O3), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide ...

This means that: there are 8 protons in the nucleus of every oxygen atom no other element has atomic number 8 A second number is needed to fully describe an atom. This number is called the mass ...

Using hard X-ray photoemission spectroscopy, researchers revealed how oxygen vacancies and structural disorder influence ...

As summer kicks into full gear and people are spending more time outside, there's one thing on many people's minds—ticks.

Lodged in a chunk of titanium, a single oxygen atom spurs extra defects in the metal’s atomic structure. Such flaws make titanium easy to shatter, scientists report in the Feb. 6 Science.

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?

For example, Oxygen has an atomic number of 8 because it has 8 protons in its nucleus. Atomic Mass: The atomic mass of an atom is the sum of the protons and neutrons in its nucleus.
