Year 8 - Periodic Table 2

What is a group in the periodic table?

• A horizontal row of elements
• A group of metals only
• A vertical column of elements with similar properties
• A section that contains only non-metals

Which group in the periodic table contains the alkali metals?

• Group 0
• Group 7
• Group 2
• Group 1

Which of the following is a property of the noble gases (Group 0)?

• Very reactive
• Form alkaline solutions
• Very unreactive (inert)
• React violently with water

Sodium reacts with water to produce:

• Sodium oxide + hydrogen
• Sodium hydroxide + hydrogen
• Sodium chloride + water
• Hydrogen peroxide + sodium

Why are alkali metals stored in oil?

• To make them shiny
• To stop them reacting with water and oxygen in the air
• To cool them down
• Because oil makes them more reactive

What does the word inert mean?

• Highly explosive
• Reacts only with water
• Unreactive
• Changes state easily

Where are metals and non-metals found on the periodic table?

• Metals are on the left; non-metals are on the right
• Metals are on the right; non-metals are on the left
• Metals are at the top; non-metals are at the bottom
• They are randomly placed

Is hydrogen a metal or non-metal?

• Metal
• Non-metal
• Both
• Depends on the reaction

What is a period in the periodic table?

• A vertical column
• A diagonal row
• A group of gases
• A horizontal row

The halogens are found in which group of the periodic table?

• Group 1
• Group 7
• Group 0
• Group 2
