Intermolecular Forces
What does it mean if a molecule is polar?
The molecules have opposite charges.
What are the different phases of water?
Solid, liquid, and gas.
What are examples of ceramics?
Glass, pottery, brick, tiles, or cement.
What are Covalent bonds?
Bonds between non-metals.
What does it mean if a molecule is non-polar?
The molecules are equally charged.
What is Cohesion?
When the same molecule is attracted to itself.
What is a metal?
A solid material that's typically hard, shiny and fusible.
What are ionic bonds?
Bonds between metals and non-metals.
How do you know if a molecule is polar or non-polar?
Using the electronegativity difference.
What is surface tension?
The tendency of a liquid to resist external forces.
What are examples of polymers?
Name one type of Intermolecular force.
Hydrogen bonding, London disperson forces, or dipole interactions.
What is electronegativity?
Atoms ability to share electrons in a chemical bond.
What happens to the boiling point of water when theres high intermolecular forces?
High boiling point.
What are examples of semi-conductors?
copper, glass, silicone, aluminum, or sulfur.
What are Intermolecular forces?
The interacions between molecules like covalent and ionic bonds.
What is Polarity?
Whether the electrons in covalent bonds move towards or away atoms in a molecule.
What are basic properties of water?
Its cohesive, is slow to freeze and boil, adhesion, universal solvent, surface tension.
What are semi-conductors?
Materials with electric conductivity.
