When a fluorine atom gains an electron, it forms a negative ion.
When fluorine forms an ionic bond to achieve the electron configuration of neon, it gains one electron to become a fluoride anion. By gaining an electron, fluorine's outer electron shell is filled with eight electrons, similar to neon's stable electron configuration. This allows the fluorine atom to achieve greater stability.
The ion formed by a fluorine atom is called a fluoride ion, which has a charge of -1. It is formed when a fluorine atom gains an electron to achieve a full outer electron shell.
When a chlorine atom gains one electron, it forms a chloride ion with a single negative charge.
A fluorine atom that has seven electrons in its outer shell would be neutral. A negatively charged fluoride ion, Fl-, forms when a fluorine atom gains one electron so that it has an octet, or a noble gas configuration of electrons.
Fluorine forms a 1- ion because it has 7 electrons in its outer shell, this is not very stable. What is stable is a full outer shell of 8 electrons. So a fluorine atom will take an electron (which carries a 1- charge) from another atom to complete this so-called octet.
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.
hmm
it forms an ionic bond with the atom it has received an electron from.

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.
no
A fluorine atom gains one atom in order to achieve the same electron configuration as neon. In doing so, the fluorine atom forms a fluoride ion with a 1- charge with the formula F-. As a negatively charged ion, it can form ionic bonds with various positively charged ions.
One electron is lost when a lithium atom forms a compound with fluorine atoms, as lithium has 1 valence electron and fluorine can gain one electron to achieve a full outer shell.
When a chlorine atom gains one electron, it forms a chloride ion with a single 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.
When a lithium atom reacts with a fluorine atom, the lithium atom loses an electron to form a lithium cation and the fluorine atom gains that electron to form a fluoride anion. This results in the formation of lithium fluoride (LiF), an ionic compound.
