HS-PS1-1

SCUSD NGSS Curriculum Guide


 * 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.//]

Science Background for the Teacher:
[overview of relevant science background for teacher]

Key Vocabulary:

 * predict || periodic table || nucleus || proton ||
 * neutron || electron || covalent bond || ionic bond ||
 * ionization energy || metal || non-metal || reactivity ||
 * energy level || valance electron || atomic radius || electronegativity ||

Possible Assessments (formative and/or summative):
Have students predict the properties of a not-yet discovered element (for example, element 117) based on its location in the periodic table. (summative)

Key Student Activity:
Compare and contrast arrangement of electrons in the outermost energy level of various elements and note where they are located on the periodic table.

Identify trends and properties of elements based on their location on the periodic table.
