Which statement best explains why the overal change on an atom is zero

An atom has a neutral overall charge because it has the same amount of electrons as protons. Protons and neutrons have the equivalent mass. Electrons have such a little mass that this can normally be considered as zero.

Explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
