31. A) Explain the formation of Sodium chloride on the basis of the concept of
electron transfer from one atom to another atom.​

Answer 1

Answer:

A chemical bond may be defined as the  force of attraction between the atoms that  binds them together as a unit called molecule.

sodium with atomic number  11 will readily loose one electron to attain  neon’s stable electronic configuration. Similarly, chlorine has electronic  configuration 2,8,7. To get the nearest noble  gas (i.e. argon) configuration, it need one more electron. So, chlorine readily gains one  electron from other atom and obtains stable  electronic configuration. Thus  elements tend to have stable valence shell  (eight electrons) either by losing or gaining  electrons.
