Properties and Behavior of Non-Metals

The video explores the atomic structure and properties of non-metals, focusing on covalent bonds. It highlights carbon's unique bonding, the brittleness of non-metals, their poor conductivity, and interaction with light. Non-metals have low densities and melting points due to their atomic structure.

What type of bonds are primarily responsible for the properties of non-metals?

• Metallic Bonds

• Ionic Bonds

• Hydrogen Bonds

• Covalent Bonds

Why is carbon considered a non-metal despite having only four electrons in its outer shell?

• It forms covalent bonds with other carbon atoms

• It has a full outer shell

• It forms ionic bonds

• It behaves like a metal

What happens to carbon when it is struck with a hammer?

• It becomes malleable

• It conducts electricity

• It melts

• It shatters into smaller pieces

How does iodine behave when it is hit with a hammer?

• It shatters due to weak bonds

• It becomes a liquid

• It forms a new compound

• It conducts electricity

Why are non-metals poor conductors of electricity?

• Their electrons are locked in place

• They are malleable

• They have free electrons

• They have a high density

What characteristic of non-metals affects their interaction with light?

• Metallic luster

• High density

• Locked electrons that absorb specific light colors

• Free movement of electrons

Why does bromine appear reddish-brown?

• It absorbs all colors of light

• It reflects red light

• It has a high density

• It is a metal

What is a common property of non-metals like helium and oxygen?

• High melting points

• Metallic bonding

• High density

• Low density and low melting points

Why do gases like oxygen have low densities?

• They form metallic bonds

• Their atoms are not strongly attracted to each other

• They are tightly bonded

• They have high melting points

What happens to phosphorus molecules due to their weak bonds?

• They remain tightly packed

• They conduct electricity

• They form a dense solid

• They spread out and have low density
