This NGSS-inspired activity focuses on the relationship between the location of an element on the Periodic Table and its tendency to form an ionic, covalent, or metallic bond with other elements on the table. The activity aligns with the HS-PS1-1 standard of the Next Generation Science Standards.
This NGSS-inspired task includes five scaffolded activities that begin with an investigation of the sub-structure of atoms and ions. Then students explore the formation of ions by atoms of main group elements. Finally, the last two activities pertain to the ratio by which atoms of elements combine to form ionic compounds. Each activitiy places an emphasis upon the connection between the chemistry concept and the family properties of elemental groups on the Periodic Table.
This NGSS-inspired task includes five activities that identify trends in atomic size and metallic character (ease at which electrons are lost), that use trends in electronegativity to predict the type of bond formed between a given element and three other elements in the table, and relate trends in outer shell electron arrangements to the formula of a molecular compound. The activity aligns with the HS-PS1-1 standard of the Next Generation Science Standards.
