In the case of oxygen-28, the scientists involved in the study proposed that further research would require observing the ...

When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...

At the heart of most large galaxies, including our own Milky Way, lurks a supermassive black hole. These cosmic giants ...

Since this atom has a total of eight electrons, it also has eight protons. The atom with eight protons in its nucleus (atomic number 8) is oxygen. Each energy level holds a certain number of electrons ...

Biconcave shape to provide a large surface area for the diffusion of oxygen. No nucleus to provide more space for haemoglobin. White blood cell Defend the body against disease. Large cells that ...

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by ...

Image of the emission of 4 neutrons (blue spheres) from the exotic nucleus oxygen-28, which consists of 8 protons (red spheres) and 20 neutrons.

Red blood cells for example, have no nucleus, so they can hold more oxygen. They're also biconcave or disc-shaped to absorb oxygen more quickly and rounded to flow easily through tiny capillaries.

Within the nucleus of every cell are long strings of ... It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus. Combinations of these atoms form the sugar ...
