Metals: Location and Reactivity

Priya is organizing a collection of elements for her science project. She notices that some elements are shiny, good conductors of electricity, and are mostly found on one side of the periodic table. Which of the following statements is true about the metals Priya is observing?

• Metals are found only on the right side of the periodic table.

• Metals make up the majority of the periodic table.

• Metals are always non-conductors.

• Metals are only found in the top row of the periodic table.

Olivia is helping her teacher organize materials in the science lab. She needs to separate the metals from the non-metals. What are some common properties of metals that Olivia should look for?

• Dull appearance, poor conductors, brittle

• Shiny appearance, good conductors, malleable

• Shiny appearance, poor conductors, brittle

• Dull appearance, good conductors, malleable

Where are metals primarily located on the periodic table?

• On the right side only

• In the top row only

• On the left side and middle

• On the bottom row only

Which group in the periodic table contains the alkali metals?

• Group 1

• Group 2

• Group 3

• Group 16

What type of metals are found in Group 2 of the periodic table?

• Alkali metals

• Alkaline earth metals

• Transition metals

• Metalloids

If a metal is classified as a transition metal, in which group is it most likely to be found?

• Group 1

• Group 2

• Groups 3-12

• Group 18

Where are the most reactive metals located on the periodic table?

• Right side and top

• Left side and bottom

• Middle and top

• Right side and bottom

Why would group 1 metals be so reactive? (Choose the best explanation.)

• They have a full outer electron shell.

• They have only one electron in their outer shell, which is easily lost.

• They are located in the middle of the periodic table.

• They are non-metals.

Refer to the diagram showing trends in metal and non-metal reactivity. Which direction does metal reactivity increase on the periodic table?

• Right and top

• Left and bottom

• Middle and top

• Right and bottom

Where are metals located on the periodic table?

• On the left and in the center of the periodic table.

• Only at the top of the periodic table.

• On the right side of the periodic table.

• Scattered randomly throughout the periodic table.
