Answer:

B. An electron from the sodium atom moves to the fluorine atom forming two ions.

Explanation:

In forming this ionic compound NaF, an electron is transferred from the sodium atom to the fluorine atom and two ions are formed.

This is the mechanism of forming ionic or electrovalent bonds.
Every atom desires to have the configuration of noble gases.
When a metal and non - metal approaches one another, the electronegative specie prefer to get electrons to complete its octet.
The electropositive metal will prefer to lose electrons.
In the case of NaF, Na will lose an electron to become isoelectronic with Ne.
Fluorine gains the electron and becomes isoelectronic with Ar
Two ions the attracts one another with an electrostatic force will now form.

A branch of science which deals with the study of chemicals is called chemistry.

The correct answer to the question is B.

The reaction between the acid and base is called a neutralization reaction and forms the salt.

Salt is an ionic compound in which cation and anion joined together to form a compound. In an ionic compound, one element gives electrons to the other element to complete the outer shell and make a bond. In the question, sodium has more electrons and gives them to fluorine.

Hence, the correct option is B that is An electron from the sodium atom moves to the fluorine atom forming two ions.
