Question

Write the electronic configuration
of magnesium and oxygen and explain the formation of magnesium oxide by electron transfer. State the type of bond formed.Explain with reason two physical properties of compound formed by this bonding.​

Answer 1

Answer:

the bond is covalent bond

mg = 2,8,2

o2=2,8

physical properties

• *the elements formed are solid and somewhat hard

• *they have high melting n boiling point

• *they dont conduct ectricity in solid state but conducts in molten state

Answer 2

Answer :

• Electronic configuration of Mg (12) : 2, 8, 2.
• Electronic configuration of O (8) : 2, 6.

Formation of MgO :

• Mgo is formed by the ionic bonding between $\rm{Mg^{2+}}$ cation and $\rm{O^{2-}}$ anion.

• During the formation of MgO, magnesium loses 2 electrons and oxygen gains 2 electrons. Refer to the attached image for more information.

Type of bond formed :

• Ionic bond.

• Definition : Ionic bond or electrovalent bond is a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

$\hrulefill$

Physical properties of ionic compounds :

1. High melting and boiling point : This is because a considerable amount of energy is required to break the strong inter-ionic attraction.
2. Ionic compounds are solid and hard : This is due to the strong force of attraction between the positive and negative ions.
