Question

write the electron dot structure for sodium and chlorine atoms.How do these from a chemical bond? Name the type of bond so formed . Why does a compound so formed have high melting point ​

Answer 1

Electron dot structure for sodium and chlorine atom can be seen in the image attached.

Sodium have one electron in its valence shell and chlorine have 7 electrons in its valence shell and it requires only one electron to complete its octet that electron is donated by sodium and thus a bond is formed between the two atoms.

The bond that is formed is known as an ionic bond and as a ionic bond is formed , this compound is an ionic compound , it has a high melting poin

I Hope this answer helpful

Answer 2

The outer shell electron of sodium is transferred to chlorine outer shell in order to attain complete octet by sodium and chlorine both. 

The type of bond they form is ionic bond. 

This bond is very strong through out the the lattice structure of sodium chloride which is reason for high melting point of sodium chloride.
