The electron configuration of fluorine is 1s22s22p5. To form the F- ion (fluoride ion), one electron is gained to achieve a full valence shell. Therefore, the missing number of electrons in the electron configuration of F after gaining one electron is 1.
An example of an ion is a sodium ion (Na+), which has lost one electron to become positively charged.
An ion is an atom with a couple of extra electrons, or which is missing a couple. So when common table salt (NaCl) dissolves in water, it comes apart as a positively charged sodium ion Na+ which is missing an electron, and a negatively charged Cl- ion which has the extra electron from the sodium atom.
If an ion gains an electron that means the ion will be negatively charged.The name of that ion is called anion. On the other hand, if it loses and electron the ion will be positively charged, and the name of that ion is called cation.
An example of an atom is carbon (C), which has six protons. An example of an ion is a chloride ion (Cl-), which has gained an electron. An example of an isotope is carbon-14 (14C), which has 8 neutrons instead of the usual 6.
An atom with one extra electron is called an anion, while an atom with one missing electron is called a cation.
Hydrogen sometimes accepts an electron and forms a negative ion, while other times it donates an electron and forms a positive ion.

Chloride is an ion of chlorine plus one electron. In solution, calcium is an ion missing two electrons.
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
Chloride ion (Cl-) is an example of a negative ion. When chlorine gains an electron, it becomes negatively charged.
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
A Cation is a positive ion formed after removal of electron(s). For example, Fe^+2
Hydrogen with its electron missing is a positive ion and like all ions is very chemically active, trying to become uncharged again.
