There are the same number of these two particles in an atom

Protons and electrons

Explanation:

Atoms that have a neutral charge have an equal number of protons and electrons. Protons are positively charged and electrons are negatively charged, so to cancel out all charges, the number of both these particles must be equal. If there is an unequal amount, then it is called an ion. Ions are atoms that have either a negative or positive charge because the amount of protons and electrons is not balanced.

answer: your mm

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.
