Atoms are the smallest unit of matter that still has properties of the material it's made of. Atoms are made of protons, neutrons and electrons. The number of protons determines what element the atom is. Atoms are the building blocks of all matter, including living things!

Atom: an atom is the smallest unit of matter that constitutes a chemical element. Atoms are made up of protons, neutrons, and electrons. Nucleus: the nucleus is a dense structure at the center of an atom that contains protons and neutrons. Electron: electrons are found in the cloud surrounding the nucleus. They have a negative charge and are the smallest charged particles in an atom

Question: What does an atom look like and what are its parts? Clues: • An atom is made up of three different types of particles. • Protons and neutrons are located in the nucleus of the atom while electrons move around the nucleus. • The nucleus of an atom is small compared to the size of the entire atom. In pairs: Select and solve one of the tasks: A. Draw a model of an atom and include the nucleus and electrons. B. Describe how the protons, neutrons, and electrons interact with each other.
