Periodic Table 2

Multiple Choice

Why do you think scientists use the term 'families' when talking about the periodic table?

• Because elements are related by similar properties

• Because elements are grouped by color

• Because elements are grouped by size

• Because elements are grouped by atomic number only

Open Ended

Explain how the concept of 'families' in the periodic table helps us understand the behavior of elements.

Multiple Choice

Which of the following are properties of alkali metals?

• They are shiny and can be cut with a knife.

• They are found in the last column of the periodic table.

• They have 8 valence electrons.

• They are gases at room temperature.

Multiple Choice

Why are alkali metals never found as free elements in nature?

• They are very reactive and always bond with other elements.

• They are stable and do not react with other elements.

• They are only found in gaseous form.

• They are always found in water.

Open Ended

Explain how the number of valence electrons affects the reactivity of an element.

Multiple Choice

Which of the following is a property of alkaline earth metals?

• They are found uncombined in nature

Multiple Select

Which of the following statements about the Halogen Family is/are correct?

• They have 7 valence electrons.

• They are the most active non-metals.

• They are always found free in nature.

• They react with alkali metals to form salts.

Fill in the Blanks

Noble gases are un-reactive because their outermost energy level is
