Period 3 From Metal to Noble Gas
Written by Adi Ackerman, Head Teacher
"Period 3 From Metal to Noble Gas" is written for 7th Grade (Ages 12-13). A 6th grader who is already steady on matter can use it too, and an older student can use it as a short review.

7th grade science worksheet: graph melting points from sodium to argon, mark where metals end and link valence electrons to current. Answer key included. Part of our periodic table matter collection.
How do I use this worksheet?
Begin with the blank table and the history sheet, then move through the family sheets one at a time. Use the crossword, move card game and review quiz for practice, and keep the reference page in student notebooks.
What students will practice
- Students will draw bars for melting points, including values below zero.
- Students will mark where metals end on the graph with a dashed line.
- Students will link valence electrons to which elements carry current.

FAQ
How do I use this periodic table worksheet?
⌄
Begin with the blank table and the history sheet, then move through the family sheets one at a time. Use the crossword, move card game and review quiz for practice, and keep the reference page in student notebooks.
What does this worksheet teach?
⌄
Graph melting points from sodium to argon, mark where metals end and link valence electrons to current. The directions on the page read: Read the text and table. Draw a bar for each element's melting point, going below zero for negative values. Draw a dashed line where metals end. An answer key is included.
Can I use this periodic table worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade matter, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is the difference between a group and a period?
⌄
A period is a row and a group is a column. Students use this on the move card game, the clue hunt and the review quiz.
Which periodic table trends do students graph?
⌄
Students graph melting point down group 1, atomic radius across period 2 and down group 1, and melting points across period 3. Each graph is followed by questions that ask for the trend and its reason.
Are there answer keys for the periodic table worksheets?
⌄
22 of the 23 sheets have answer keys. The periodic table reference page is made for notebooks and has no key.
Do the sheets cover how Mendeleev built the table?
⌄
Yes. One sheet places Döbereiner, Newlands, Mendeleev, Moseley and Seaborg on a timeline and asks how close Mendeleev's predictions came.
