Does the Potential Energy increase during Chemical Bonding?

Click For Summary
SUMMARY

The discussion centers on the concept of potential energy during chemical bonding, specifically referencing the formula U=1/2(k*q1*q2)/r. Participants clarify that as atoms approach each other, their potential energy decreases, contrary to the initial claim that it increases. The confusion arises from the interpretation of charges (q1 and q2) and the neutrality of atoms. A foundational understanding of quantum mechanics and atomic orbitals is essential to grasp the behavior of potential energy in bonding scenarios.

PREREQUISITES
  • Understanding of potential energy equations in chemistry
  • Basic knowledge of quantum mechanics
  • Familiarity with atomic and molecular orbitals
  • Concept of atomic neutrality and charge interactions
NEXT STEPS
  • Study the principles of quantum mechanics related to chemical bonding
  • Explore the concept of atomic and molecular orbitals in detail
  • Learn about the role of potential energy in chemical reactions
  • Investigate how charge interactions affect atomic behavior
USEFUL FOR

Chemistry students, educators, and professionals interested in understanding the principles of chemical bonding and potential energy dynamics.

Hi All,
The Potential Energy for two chemically bonding atoms is defined by ,U=1/2(k*q1*q2)/r

So it means that when the atoms approach each other then, their Potential Energy will increase.
Where am I doing wrong?

I will be thankful for help!

Who defines it like that? What are q1 and q2? The charges? Atoms are neutral.

The potential energy decreases in bonding, but to understand why you need to know something about quantum mechanics, and atomic and molecular orbitals. Have you studied this?

Is that always the case?
