What is an atom? A basic unit of matter consisting of dense nuclease surrounded by a negatively charged electron.
What are the particles that make up an atom? Protons, neutrons and electrons. Electrons are a negative charge and are tiny in light weight. Protons carry a positive charge are are more heavy. Neutrons carry a neutral charge of zero.
What is the size of an atom? An atom is around. 1 nanometer or 100 pictometers.
