Answer:

A

Explanation:

This kind of bond is known as an ionic bond and is based on electrostatic forces between two charged molecules/atoms. To achieve stable configuration, sodium (2.8.1) transfers its valence electron to chlorine that also needs one electron to achieve stable configuration (2.8.8), and combine in an ionic bond.

Answer: The correct answer is Option A.

Explanation:

Sodium is the 11th element of the periodic table having electronic configuration of [tex][Ne]3s^1[/tex]

This element will loose 1 electron in order to attain stability and will form [tex]Na^+[/tex] ion.

Chlorine is the 17th element of the periodic table having electronic configuration of [tex][Ne]3s^23p^5[/tex]

This element will gain 1 electron in order to attain stability and will form [tex]Cl^-[/tex] ion.

These two elements form ionic compound by transferring of electrons from sodium atom to chlorine atom.

Hence, the correct answer is Option A.
