States of Matter Let’s Take a Microscopic View of Different States of Matter. http://www.harcourtschool.com/activity/states_of_matter/
Atoms • All matter, such as solid, liquid and gases, is composed of atoms.
Atom Atoms have three basic parts • Proton • Neutron • Electron
Atoms Nucleus – is the center. There are two types of charges found in the nucleus. • Protons • Neutrons
Protons & Neutron • Protons have a positive charge. • Neutrons have no charge.
Electrons • Electrons have negative charge. • They are found circling the nucleus in paths called orbits.
Facts on Atom • Protons have a positive charge equal in magnitude to the electron’s negative charge. • Neutrons have the same mass as a proton, but no charge.
Atomic Number & Atomic Mass • Atomic Number – the number of protons in an atom. • Atomic Mass = Number of protons + number of neutrons. • Symbol – one or two letters that stand for the name of the element.
