An atom that has gained one or more electrons is called an anion. It is also known as a negative ion. A positive ion, or a cation is one that has lost one or more electrons. More »

When an atom loses an electron, its overall charge becomes more positive by one. For example, a neutral atom would have a charge of positive one after losing an electron. More »

A hydrogen atom has one electron. The hydrogen atom is simply made up of one electron and one proton that are bound together by an electromagnetic force. More »

The atomic radius of an atom is determined by the total number of electrons, electron shells and protons in an atom. Protons are located in the nucleus of an atom and create an effective nuclear charge. Electrons within ... More »

A negatively charged atom is called an anion. An anion forms when an atom gains electrons from another atom. Atoms are generally neutral, but they take on a charge when they gain or lose electrons. More »

Ionization energy is an elemental property defined as the amount of energy it takes to remove the outermost electron of a gaseous atom. Cesium has the lowest ionization energy of all the elements, as it takes the least e... More »
