HS-PS1-1 Evidence Statement

Physical Science: Matter and Its Interactions - Evidence Statement 1

HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

[Clarification Statement: Examples of properties that could be predicted from patterns could include reactivity of metals, types of bonds formed, numbers of bonds formed, and reactions with oxygen.] [Assessment Boundary: Assessment is limited to main group elements. Assessment does not include quantitative understanding of ionization energy beyond relative trends.]


For more specific information, including ways this performance expectation can achieve three-dimensional learning, please see this NGSS Evidence Statement.
