How do you think about the answers? The atom is the smallest part of matter that represents a particular element. Let me explain: An atom consists of a nucleus with positive charge and electrons with negative charge that both attract each other. For an atom, the number of protons = number of electrons. Masses for the three subatomic particles can be expressed in amu (atomic mass units) or grams. Under a vacuumed environment, these devices produce invisible rays that originate from a negative electrode (cathode) and continue to a positive electrode (anode).
