The charge on a fluoride ion is -1.
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
'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'.
A fluorine atom changes into a fluoride ion by gaining one electron and developing a 1- charge.
Because it has an extra electron
It is hydrogen fluoride with chemical formula HF. It contains one fluoride atom and one hydrogen atom per hydrogen fluoride molecule.
it gains an atom
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
Fluoride is an ion consisting of a single atom of fluorine atom with a -1 charge. The fluoride in toothpaste and other dental products is sodium fluoride , consisting of sodium, and fluorine.

Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
Because it has an extra electron
It is hydrogen fluoride with chemical formula HF. It contains one fluoride atom and one hydrogen atom per hydrogen fluoride molecule.
Fluoride is fluorine's anion; it is a fluorine atom with an extra electron, giving it a negative charge. Thus, the compounds contained within it, like those of any atom, would be protons, neutrons, and electrons. The protons and neutrons are composed of quarks. Fluroide can bond with metallic cations to form salts, such as sodium fluoride, which is often found in toothpaste.
what does an atom have in common with an ion?
Fluoride ion is a singly negative ion.
The cadmium ion has a 2+ charge and each fluoride ion has a 1- charge, so two fluoride ions are needed to balance the 2+ charge of cadmium. Two F- ions provide a total negative charge of 2- to balance the 2+ charge of cadmium.
