A covalent bond between two atoms represents what kind of energy?
a. Kinetic energy
b. Potential energy
c. Mechanical energy
d. Solar energy
Introduction:
The covalent bond is formed by the sharing of one or more electron pairs between the two atoms. Usually, the two atoms involved in the covalent bond have either almost equal electro negativity or there is a large difference between the electro negativity. The formation of the covalent bond allows the atoms to achieve their stable configuration.
Answer to Problem 1U
Correct answer:
The covalent bond, which is formed between the two atoms, contains the potential energy. Therefore, option b is correct.
Explanation of Solution
Reasons for the correct statement:
The covalent bond is formed by the sharing of one or more electron pairs between the two atoms. The covalent bond stores a large amount of energy in the form of potential energy. It requires energy to break the bond.
Option b is given as "potential energy."
As the energy stored in the covalent bond is a form of potential energy, option b is the right answer.
Reasons for the incorrect statements:
Option a is given as “kinetic energy.”
The energy of motion is known as kinetic energy. So, it is a wrong answer.
Option c is given as “mechanical energy.”
The mechanical energy is the sum total of the kinetic and the potential energy. It is conjugated to the position and the motion of the object. So, it is a wrong answer.
Option d is given as “solar energy.”
The heat and the radiant energy obtained from the sun is termed as the solar energy. So, it is a wrong answer.
Hence, the options a, c, and d are incorrect.
The covalent bond stores energy in the form of potential energy. Energy is required to break the bond between two atoms.
