Question

How should you change this image to represent an ionic bond between sodium and fluorine?

Answer 1

Answer: The correct answer is Option C.

Explanation:

Ionic bond is formed when complete transfer of electrons takes place from one atom to another atom. The atom which donates electrons is known as electropositive atom and the atom which accepts electron is known as electronegative atom.

This bond is usually formed between a metal and a non-metal.

Sodium is the 11th element of the periodic table with electronic configuration $1s^22s^22p^63s^1$

This element will loose 1 electron easily to form stable electronic configuration.

Fluorine is the 9th element of the periodic table with electronic configuration $1s^22s^22p^5$

This element will gain 1 electron easily to form stable electronic configuration.

So, sodium will transfer 1 electron to fluorine. Hence, the correct answer is Option C.

Answer 2

C. Move one electron from sodium to fluorine, because the element with the smallest amount of valence electrons is the one that give away the electrons, it is easier to add one to seven than it is to add 7 to one. I just learned this in physics, hope it helps! If you need more explaining I can do that.
