When fluorine reacts with a metal it forms an F-ion The fluorine atom has gained an electron and undergone?

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.


When a fluorine atom gains an electron it form a?

hmm


What does an atom do when it gains an electron?

it forms an ionic bond with the atom it has received an electron from.


What happens to an atom of fluorine F when it forms an ionic bond in which it has the same electron configuration as the noble gas neon?

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?

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.


Why fluorine atom is smaller than fluoride ion?

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.


What kind of bond forms when an atom loses or gains an electron?

no


What happens to an atom of fluorine when it forms an ionic bond in which it has the same electron configuration as neon?

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.


How many electrons are lost when a lithium atom forms a compound with fluorine atoms?

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.


What is the name of a chlorine atom gains one electron?

When a chlorine atom gains one electron, it forms a chloride ion with a single negative charge.


What is the difference between a Fluoride ion and a Fluorine atom?

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.


What happens to he lithium atom when it reacts with fluorine atom?

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.
