Why are covalently bonded materials generally less dense than metallically or ionically bonded ones

Chemistry
1 answer:
Snowcat [4.5K]3 years ago
3 0

Explanation:

It is known that ionic compounds are formed by transfer of electrons from one atom to another. And, during this type of bonding there occurs long range of bonding structure due to the nature of ionic bonds.

As these also contain opposite charge hence, they are more tightly packed with each other.

Whereas in covalent bonding the atoms tend to share electrons due to which they are not tightly packed with each other. As a result, empty spaces are created between the bonding structure which tends to reduce the density of the material.

Therefore, covalently bonded materials generally less dense than metallically or ionically bonded ones.

The sum of pH and pOH for any aqueous solution equals .
Vsevolod [243]

Answer:

pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7. Thus the sum of pH and pOH is 14
