cloud of negatively-charged electrons. By definition, atoms are neutral entities because the positive charge of the nucleus is cancelled by the negative charge of the electron cloud. However, the gain or loss of an electron can lead to the formation of an ion, also known as a charged atom....

Electrons have a negative charge. The number of electrons is equal to the number of protons: so negative charges cancel out the positive charges. Atomic Number= number of protons (also number of electrons) Atomic Weight = number of protons + number of neutrons Atomic weight is the average ...
