Front

What are the three main states of matter?

Back

Solid, Liquid, Gas

Front

What is the characteristic of a solid state of matter?

Back

Particles are closely packed together and vibrate in fixed positions.

Front

What is a liquid state of matter characterized by?

Back

Particles are close together but can move past one another, allowing liquids to flow.

Front

What defines a gas state of matter?

Back

Particles are far apart and move freely, filling the container they are in.

Front

What is a chemical bond?

Back

A lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is an ionic bond?

Back

A type of chemical bond formed through the transfer of electrons from one atom to another.

Front

What is a covalent bond?

Back

A type of chemical bond formed when two atoms share one or more pairs of valence electrons.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are involved in forming bonds between atoms, determining the chemical properties of elements.

Front

What properties do ionic compounds typically exhibit?

Back

High melting points and the ability to conduct electricity when molten or dissolved in water.

Front

Why do ionic compounds conduct electricity when dissolved in water?

Back

Because the ions are free to move in the solution.
