Grade 8, Science Std 3.0: Determine the number of protons, neutrons, and electrons, and the mass of an element using the periodic table. • Using data about the number of electrons in the outer shell of an atom to determine its reactivity. • Comparing and contrasting isotopes with commonly occurring elements.

Lesson Plans: Periodic Table Bingo In this lesson students will learn to interpret the periodic table through a game format. Isotopes of Pennies To demonstrate that isotopes of an element have different masses; that isotopes are atoms of the same element that have different numbers of neutrons; and that atomic mass is the weighted average of the naturally occurring isotopes of an element. Why Are Electrons Important? The student will be able to write the electron configuration of any element, given the atomic number. Given the location of an element on the periodic table, the student will be able to give the highest energy level the valence electrons are on, and how many valence electrons it has. The Numbers Game Find the atomic number, mass number, proton number, neutron number, and electron number. Yumminium To get students to think about the periodic table and that new elements are being discovered all the time. Students will be asked to calculate the atomic mass and number of neutrons of Yumminium.
