When a fluorine atom gains an electron to form the fluoride ion?
The electron configuration of a neutral fluorine atom is 1s22s22p5 . When a fluorine atom gains one electron, it becomes a fluoride ion with 10 negatively charged electrons and 9 positively charged protons, which gives it a 1− charge.
How does fluorine form an ion?
A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
Will F gain or lose electrons when forming an ion?
A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge. It has become a negative ion. The positive lithium ion and the negative fluoride ion will now be attracted to each other.
What is the charge of a fluorine ion?
-1

What happens when a fluorine atom gains an electron?
A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1. Click to see full answer.
What makes up the radius of a fluorine atom?
A fluorine atom has nine electrons and nine protons. An outer electron is partially screened by the other eight electrons. It “sees” only an effective charge of +5.2, and this determines its atomic radius. If we add a tenth electron, it is now partially screened by the other nine electrons.
When does an element gain an electron it gives off energy?
The electron affinity of an element is the energy given off when a neutral atom in the gas phase gains an extra electron to form a negatively charged ion. A fluorine atom in the gas phase, for example, gives off energy when it gains an electron to form a fluoride ion.
How are lithium and fluoride ions attracted to each other?
The positive lithium ion and the negative fluoride ion will now be attracted to each other. They can join together, or bond, to form lithium fluoride. Note: Chemists sometimes draw the electrons around atoms in shells (as in picture 3.3).
