NGSS dimensions

Science and engineering practices Developing and using models: Use a model to predict the relationships between systems or between components of a system.

Disciplinary core ideas Structure and properties of matter: Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. Structure and properties of matter: The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.

Crosscutting concepts Patterns: Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena.
