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 ...

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.

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 ...

Transmission electron microscopy is a general type of electron microscopy that generates an image of the internal structure of a thin sample using a beam of electrons to achieve much higher ...

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 ...

Scientists have set up and observed a single electron bond between two carbon molecules. A traditional “single bond” is actually two electrons—one from each atom. This is one electron.

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 ...
