Estimate the binding energy of a kcl molecule by calculating the electrostatic potential energy when the k+ and cl− ions are at their stable separation of 0.28 nm. assume each has a charge of magnitude 1.0e.

binding energy, E = 0.513 eV

Explanation:

It is given that,

Distance between ions,

Charge,

Binding energy can be calculated using potential energy as :

or

E = 0.513 eV

So, the binding energy of a KCl molecule is 0.513 eV. Hence, this is the required solution.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

i think so it’s will be b yes i believe its
