fluoride ion
Fluoride ion (F-) is not an element, but an ion formed from the element fluorine (F). Fluorine is a chemical element on the periodic table, while fluoride ion is a negatively charged particle resulting from the gain of an electron by a fluorine atom.
The only possible ion of fluorine is: F-It's called a fluoride ion.
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
Sodium, Na, is in group 1 of the periodic table, so to achieve a complete valence shell, it forms a cation with a charge of 1, Na1+.
There are 9 electrons in the atom without a charge, . The Fluorine ion (F -), has 10 electrons.

'Fluoride atom'. ???? The fluorine ATOM is 'F' The fluorine molecule is 'F2'. The Fluoride ION is 'F^-' NB When an atom becomes a charged species, it is no longer an atom , but an ION. The suffix '--ide' indicates it is an ion, not an atom. So 'Fluoride atom' is a nonsense. It is either 'Fluoride ion' or Fluorine atom'.
When fluorine reacts with a metal, it gains an electron to form the fluoride ion (F-). This process is called reduction, as the fluorine atom is gaining electrons.
The ion formed by a calcium atom is called a calcium ion, which has a 2+ charge.
A fluorine atom can change into a fluorine ion by gaining one electron to achieve a full valence shell. This extra electron gives the fluorine atom a negative charge, transforming it into a fluoride ion.
Fluoride Ion
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
The fluoride atom has 7 electrons in its outer shell (9 in total) but the ion of fluorine has any number of electrons in the outer shell. eg. F+ = the normal fluorine atom but with one less electron.
-1.
Fluorine atom is smaller than fluoride ion because when fluorine gains an electron to form the fluoride ion, it adds an electron in the outermost shell which increases the electron-electron repulsion, causing the electron cloud to expand. This expansion results in the fluoride ion being larger in size compared to the fluorine atom.
Sodium, Na, is in group 1 of the periodic table, so to achieve a complete valence shell, it forms a cation with a charge of 1, Na1+.
