Question

Explain the formation of the ionic compound between metal and non metal with transfer of electrons with magnesium as metal and chlorine as non metal to illustrate the answer give reaction

Answer 1

Magnesium, whose atomic number is 12, has 2, 8, 2 configuration. It has two electrons in its valence shell. Chlorine has an atomic number of 17 and an electronic configuration of is 2, 8, 7. It has seven valence electrons. Chlorine is one electron short of the argon configuration (2,8,8) while magnesium has two electrons in excess of the neon configuration (2, 8,). Accordingly, one atom of magnesium will find two atoms of chlorine to transfer its two electrons to (one to each) as shown above:

The Mg2+ and the two Cl- so formed, then form ionic bonds between them.

In terms of Lewis dot structure.

Answer 2

as magnesium had a double positive charge and chlorine double negitive charge so they react with each other to form a new compound as positive and negitive charges attract each other.
Mg + Cl = MgCl( magnesium chloride)
