8th+Grade+Chemistry


 * Established Goals: **

 (5) Matter and energy. The student knows that matter is composed of atoms and has chemical and physical properties. The student is expected to: (A) describe the structure of atoms, including the masses, electrical charges, and locations, of protons and neutrons in the nucleus and electrons in the electron cloud; (B) identify that protons determine an element's identity and valence electrons determine its chemical properties, including reactivity; (C) interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements; (D) recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts; (E) investigate how evidence of chemical reactions indicate that new substances with different properties are formed; and 
 * (F) recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass. ||
