The Periodic Table Quiz Part 1

Some properties of four elements, P, Q, R and S are shown in the table. Two of these elements are in Group I of the Periodic Table and two are in Group VII.

Which element is included into group VII?

• P

• Q

• R

• S

Answer explanation

• - Group I elements (alkali metals) react vigorously or explosively with water.

  • P reacts vigorously.

  • R reacts explosively.

  • These suggest that P and R are alkali metals (Group I).

• - Group VII elements (halogens) are typically nonmetals and can exist as liquids or solids at room temperature.

  • Q does not react with water and is a solid.

  • S dissolves, giving a colored solution and is a liquid.

  • Halogens, such as bromine (Br), exist as a liquid at room temperature.

  • This suggests S is a Group VII element (likely bromine).
