How does electronegativity affects the type of intramolecular bond that is formed between atoms
Effectus [21]

Answer:

If the electronegativity difference between bonded atoms are too much high ionic bonds are formed if the electronegativity diference is 0.4 or less than 0.4 non polar covalnet bond formed the difference greater than 0.4 polar covalent bond formed.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

Why is it not correct/precise to say "a molecule of salt?"
Fynjy0 [20]

It is not correct to say " a molecule of salt " because salt is a compound.

Explanation:

  • As we know a molecular bond is present in each molecule.
  • Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
  • On the other hand it is not considered as a molecule as it is not holding an ionic bond.
  • As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
