5.
Sodium and chlorine combine. In what ratio, Luz?
- 1 to 7, as NaCl₇
- 1 to 1, as NaCl
- 2 to 1, as Na₂Cl
6.
Milo says lithium is the most reactive alkali metal because it is first. Agree or disagree?
- Disagree: reactivity rises down the group
- Agree: lighter metals react more
- Agree: the first one reacts most
7.
Pia says halogens are unreactive like noble gases. Agree or disagree?
- Disagree: they react readily
- Agree: halogens have full shells
- Agree: both are gases
8.

- An alkali metal
- A metalloid
10.
Which describes a typical nonmetal, Zee?
- Shiny and bendable
- A poor conductor
- A good conductor

Families of elements and their properties. Every version has 10 questions, and the answer key prints on the second page.

I can name the families (alkali metals, alkaline earth metals, halogens, noble gases, transition metals) and their valence electrons.
I can read family trends from data: alkali melting points fall and halogen boiling points rise down the group.
I can predict a middle element's property from its neighbors and compare densities.
I can predict ions and reactivity from valence electrons, and place metals, nonmetals and metalloids.

Standard: HS-PS1-1

alkali metals: Group 1 metals, each with 1 valence electron

alkaline earth metals: Group 2 metals, each with 2 valence electrons

halogens: Group 17, each with 7 valence electrons

noble gases: Group 18, with full outer shells

metalloid: An element with properties between metals and nonmetals

Your child added the melting points. How much lower one is than the other is a difference: subtract.

Your child added the neighbors but didn't halve. The middle element's value is predicted by the average, sum ÷ 2.

Your child divided the smaller by the larger. To say how many times denser, divide the denser metal by the less dense one.

What is the most common mistake with families of elements and their properties?

Your child added the melting points. How much lower one is than the other is a difference: subtract.

Are these 10th grade science worksheets free to print?

Yes. All 6 printable versions at each level are free to print, with the answer key, and no account is needed.
