Analyzing and Interpreting Data
Crosscutting Concepts
Patterns
Knowledge
Students know:
- The total number of atoms of each element in the reactant and products is the same.
- The numbers and types of bonds (ionic, covalent) that each atom forms are determined by the outermost (valence) electron states and the electronegativity.
- The outermost (valence) electron state of the atoms that make up both the reactants and the products of the reaction is based on the atom's position in the periodic table.
Skills
Students are able to:
- Interpret data to determine the type of chemical reaction.
- Analyze data to determine the patterns for each type of chemical reaction.
- Balance simple chemical equations.
- Write simple binary compound formulas and names.
Understanding
Students understand that:
- The fact that atoms are conserved, together with knowledge of the chemical properties of the elements involved, can be used to describe and predict chemical reactions.
- There is a causal relationship between the observable macroscopic patterns of reactivity of elements in the periodic table and the patterns of outermost electrons for each atom and its relative electronegativity.
