What can account for the increased potential energy when atoms are close together?

question options:

a. their opposite charges

b. electron repulsion

c. the breaking of a bond

d. proton to proton repulsion

A. their opposite charges.

Explanation:

the potential enrgy is  due to the position. it is related to the structural arrangement of molecules . therfore the opposite charges play an important role in maintaining that structural arrangemnet of atoms.

its first and third is your answer i did the qustion the fourth isnt right

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
