Ch 5.3 Representative Groups

Ch 5.3 Representative Groups

Author: deirdre carney
  • Relate the number of valence electrons to groups in the periodic table and to properties of elements in those  groups
  • Predict the reactivity of some elements based on their locations within a group
  • Identify some properties of common A group elements

Nevada Science Standards

P.12.A.2- Students know elements in the Periodic Table are arranged into groups and periods by repeating patterns and relationships

Next Generation Science Standards

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.

HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
