The basic unit of matter.
What are the particles that make up an atom, list their mass and charge?
The make up of an atom are protons, neutrons and electrons. Electrons are a negative charge and are tiny in light in weight. Protons carry a positive charge are more heavy. Neurtons carry a neutral charge of zero.
What is the size of an atom?
An atom is around 1 nanometer or 100 pictometers
What is the shape of an atom, where are the particles?
The shape of an atom is a sphere. It is determined by how the electrons orbit. The protons and neurtons are in the center.
