1. 1.

   Chlorine boils at 239.11 K and iodine at 457.55 K (PubChem). Bromine sits between them. What boiling point does the average predict for bromine, Bo?
2. 2.

   Helium boils at 4.22 K and argon at 87.3 K (PubChem). Neon sits between them. What boiling point does the average predict for neon, Esme?
4. 3.

   Using the table, which halogen is a liquid at room temperature, Jun?

   • Chlorine
   • Bromine
   • Iodine
5. 4.

   Using the table, what happens to boiling points going down group 17, Kira?

   Use the picture in question 3.

   • They rise
   • They stay the same
   • They fall
6. 5.

   Using the table, what do all four halogens share, Luz?

   Use the picture in question 3.

   • The same boiling point
   • 7 valence electrons
   • The same state

7. Read this first

   Short reading (Chemguide)

   Every alkali metal reacts with water, giving a solution of the metal hydroxide and hydrogen gas. The reactions get more vigorous going down group 1, because the single outer electron is held less tightly. This is a fact to read, not something to try.

8. 6.

   In the reading, which reacts more vigorously with water, lithium or potassium, Noah?

   • They are equal
   • Potassium, lower in group 1
   • Lithium, which is higher in group 1
9. 7.

   In the reading, why does reactivity rise going down group 1, Pia?

   • The outer electron is held less tightly
   • The atoms get smaller as you go down the group
   • The metals get colder
10. 8.

    Why are noble gases used where something unreactive is needed, Ren?

    • They are far too heavy to move around
    • Their full shells make them unreactive
    • They are metals
11. 9.

    Where are the transition metals on the table, Tala?

    • Group 1
    • Group 18
    • Groups 3–12, the d block
12. 10.

    Copper is a transition metal used in wires. Which property makes it useful there, Zee?

    • It conducts electricity
    • It is a gas
    • It dissolves in water
