Alkaline earth metal

The video tutorial covers alkaline earth metals, including beryllium, magnesium, calcium, strontium, barium, and radium. These metals are less reactive than Group 1 metals but are still high in the reactivity series. They are found as compounds in the earth's crust, and their oxides are alkaline in water.

Which of the following elements is NOT an alkaline earth metal?

• Beryllium

• Calcium

• Magnesium

• Sodium

How do alkaline earth metals compare in reactivity to Group 1 metals?

• They do not react

• They are less reactive

• They are equally reactive

• They are more reactive

Where are alkaline earth metals typically found?

• In the atmosphere

• Only in laboratories

• In their pure form in nature

• As compounds in the earth's crust

What is the nature of the oxides of alkaline earth metals when dissolved in water?

• Acidic

• Neutral

• Alkaline

• Inert

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

• They are high in the reactivity series

• Their oxides are acidic in water

• They are found in the atmosphere

• They are non-reactive
