When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

In school, you probably learned that an atom was like a little solar system with the nucleus as the sun and electrons as the planets. The problem is, as [The Action Lab] points out, the math tells ...

Modern aberration-corrected transmission electron microscopy (TEM ... directly from measurements of shifts of the individual atom positions. The conventional concept of image, which applies ...

The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...

A helium atom that has lost or gained an electron is an ion. The ion has two positive protons but one electron so it is a positive ion. Helium ion, two neutrons, two protons and three electrons.

Electrons are incredibly fast. Because of their ultrafast motions, directly observing their behavior has been challenging. Now researchers from UC San Diego’s Department of Chemistry and Biochemistry ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner ...

During the study, the engineers used the quantum property to track the electrical activity of the heart muscles and cells.

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers ...
