Question

Define ionic and covalent bonds
show the formation of magnesi
um chloride tog diagramatic representation or of electronic configuration​

Answer 1

Answer:

➡Mg forms ionic bond to Cl by donating its valence electrons to two Cl atoms. The electron configuration of Mg is [Ne]3s². It can achieve a complete octet by losing its two valence electrons to form Mg²⁺. The electron configuration of Cl is [Ne]3s²3p⁵.

➡Atomic number of Magnesium(12) atom is 12.

Electronic configuration is :

Mg = 2, 8, 2

So it contains 2 valence electron. In order to achieve the nearest noble gas configuration, it loses two electrons to form Magnesium ion.

Mg

2+ =2,8

Atomic number of Chlorine(Cl) atom is 17.

Electronic configuration is :

Cl = 2, 8, 7

So it contains 7 valence electron. In order to achieve the nearest noble gas configuration, it gains one electron to form Chloride ion.

Cl − =2,8,8

An Ionic bond is formed between Magnesium ion and two Chloride ion by complete transfer of one electron to each Chlorine ion.
