An electron from each atom feels the attraction from the other atom's nucleus. The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine.

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.

There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium (hydrogen-3): if the atom loses one or more electrons, it becomes a positively-charged ion if the atom gains one ...

“The ion trap can achieve the best qubit,” he says. “It’s just one atom floating without anything around it, so it’s a pure quantum state. That’s why the very first quantum computers ...

(The atom is then called an ion). Do not allow your atom to become too ionized. Ions are attracted to other atoms and molecules. If your atom is too ionized, it will likely zip away from you and ...
