Unformatted text preview: University of Florida Chemistry Outreach Program Building Elements! Estimated Time: 30 mins. + 10 mins. clean-up Topics: Elemental properties, Periodic Table of Elements, Subatomic particles, SC.A.1.3 Introduction: In science elements are key basic components of all reactions, living organisms, and the Earth. Every element on the periodic table of element has its own specific atomic structure. Elements are comprised of subatomic particles known as protons, neutrons, and electrons. Protons and neutrons usually reside in the nucleus of an atom while the electrons orbit in various energy levels. Protons take on a positive charge (p + ); electrons have a negative charge (e- ); neutrons have no charge (n o ). When prompting this experiment explain the structure of the atom and explain the differences between an atom and an ion. Basically, if an element has a charge on the upper right hand corner it is an ion. It is a positive ion if that charge is positive (lacking electrons) and a negative ion if that an ion....
