Two objects will never actually touch

[zapped]

Homework Statement

When an object is placed on table, the particles in the object and the particles in the table never actually touch.

Homework Equations

In a short paragraph, explain how the field model can be used to explain why the particles never touch. Refer to the strengths of the fields, and describle how individual charged particles are influenced by and react to the fields.

The Attempt at a Solution

My answer is the electrons in the two objects will repel(due to strong electrostatic repulsion) each other, and it will take an infinite amount of energy for the electrons from the 2 objects to touch.
I don't know how to relate to strength of the field, please help, thanks!

anyone can help me?

Indeed, you only need consider the valence electrons. Aside from that, there's nothing wrong with your analysis, unless you are studying quantum mechanics.
