GCSE Chemistry - Metals and Non-Metals #10

The video tutorial explains the differences between metals and nonmetals, focusing on their ion formation and electron arrangements. It highlights the reactivity of metals, which increases down the periodic table due to the distance of outer electrons from the nucleus. The video also covers the physical properties of metals, such as metallic bonding, malleability, and conductivity. Transition metals are discussed, emphasizing their ability to form multiple ions and act as catalysts in chemical reactions.

Why do metals tend to form positive ions?

• They gain electrons easily.

• They have a strong attraction to electrons.

• They have few electrons in their outer shell, making it easy to lose them.

• They have a full outer shell of electrons.

What makes metals more reactive as you move down a group in the periodic table?

• They have fewer electron shells.

• They have a higher nuclear charge.

• Their outer electrons are closer to the nucleus.

• Their outer electrons are further from the nucleus, making them easier to lose.

Which of the following is a characteristic of metallic bonding?

• Causes metals to be brittle

• Weak and easily broken

• Responsible for metals being malleable and conductive

• Only found in nonmetals

What is a common property of nonmetals?

• Good conductors of electricity

• High melting points

• Brittle and dull in color

• Malleable and shiny

What is a unique feature of transition metals?

• They are always colorless.

• They can form multiple ions and are often used as catalysts.

• They are poor catalysts.

• They can only form one type of ion.
