Explanation:

If we take a positively charged atom to a neutral one, the electrostatic force occurring between the positive charge and the valence electrons of the atom(because of Coulomb's Law) is more than the force between the valence electrons and the protons of its own atom.

Uncharged objects: In spite of what the standard says, an uncharged object will not be attracted or repelled from a charged object. Instead, the charged object will cause the uncharged object to become charged, with a positive charge on one side and a negative charge on the other side. This process is called induction.

A charged and a neutral object will also attract each other. ... If some small bits of paper were placed upon a table and the balloon were brought ... Any charged object can exert this force upon other objects - both charged and uncharged objects. ... statements will be made and explained about the nature of the electric force.

Key Concepts:

An object that has a balanced number of protons and electrons that are distributed equally will have a neutral charge.

An object that has more electrons than protons will have a negative charge.

An object that has fewer electrons than protons will have a positive charge.

An object that has its electrons concentrated on one side will have a negative charge on that side, and a positive charge on the opposite side.

Objects that have like charges will repel each other.

Objects that have opposite charges will attract each other.
