An atom is the smallest characteristic particle of an element.
What are the particles that make up an atom, list their mass and charge?
Symbol Mass Charge location in atom
Proton p+ 1 1+ Nucleus
Neutron n 1 0 Nucleus
Electron e- 1/1837 1- Outside Nucleus
What is the size of an atom?
An atom is very small. It is considered a unit of matter that consists of a dense central nucleus. Around the nucleus are negatively charged electrons. In the nucleus there are protons that are charged positively and neutrons that are electrically charged.
What is the shape of an atom, where are the particles?
An atom is a sphereical shape. The Neutron and proton particles are located in the nucleus which is in the center of the atom. The electrons are located around the nucleus.
