Mississippi Science CHE.3.1
The Standard
- CHE.3
- Students will demonstrate an understanding of the periodic table as a systematic representation to predict properties of elements.
Explore and communicate the organization of the periodic table, including history, groups, families, family names, metals, nonmetals, metalloids, and transition metals.

What This Standard Means
What Students Need to Do
- Students use the periodic table to find groups, periods, families, and regions. They explain why Mendeleev left gaps and how today's table orders elements by atomic number.
What Mastery Looks Like
- Students can find an element and name its group and period. They can identify metals, nonmetals, metalloids, and transition metals, and name families such as halogens and noble gases. They can explain what Mendeleev predicted from a gap in his table.
Common Misconceptions
- Students may mix up groups and periods, calling rows groups. Some think Mendeleev arranged elements by atomic number or that every metal is a transition metal. Others assume all nonmetals are gases.
How to Assess It
- Give students a periodic table with its labels covered. Ask them to circle a halogen and a transition metal, shade the metalloids, and write why Mendeleev left gaps.

Ways to Teach It
Give pairs element cards with atomic numbers and properties; have them arrange the cards in rows and compare their layout with a periodic table.
Show a gap in Mendeleev's table and ask, 'What might he have predicted about the missing element?'
Play a table hunt: call out 'halogen,' 'metalloid,' or 'transition metal,' and have students point to an example and justify their choice.
Have students find lithium, silicon, and copper on a phone diagram, then locate each on the table and label its region.
