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 picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

An international team of chemists has successfully created methylenedistibiranes, which are three-membered rings that have two antimony atoms and one carbon atom. In their paper published in the ...

Scientists precisely removed a gold nanocluster's core atom and outer electron, revealing how spin state affects catalytic activity without structural loss. (Nanowerk News) In a breakthrough that ...

Researchers precisely removed a gold nanoparticle's core atom and outermost electron to study how magnetic spin affects its catalytic activity. (Nanowerk News) A team of researchers from the Hefei ...

The atom is neutral as it has two positive protons and two negative electrons. A helium atom that has lost or gained an electron is an ion.
