Elements

Atom

The smallest unit of an element that retains the properties of that element.

Molecule

A group of two or more atoms bonded together.

Compound

A substance formed when two or more different atoms bond together.

Element

A pure substance made up of only one type of atom.

Periodic Table

A chart that organizes all known elements based on their properties.

Physical Properties

Characteristics of a substance that can be observed or measured without changing the substance's identity.

Chemical Properties

Characteristics that can only be observed when a substance undergoes a chemical change.

Viscosity

A measure of the thickness or resistance to flow of a liquid.

Electrical Conductivity

The ability of a substance to conduct electricity.

Corrosion

The process by which refined metal is converted to a more chemically stable form.

What are atoms made of?

Atoms are made up of three main subatomic particles: electrons, protons, and neutrons.

How do you define a physical property?

A physical property can be observed or measured without changing the identity of the substance.

What is a key characteristic of metals?

Metals have free-roaming electrons that allow them to conduct electricity.

What are elements classified by?

Elements are classified based on their chemical properties, atomic number, atomic mass, chemical symbol, and name.

What does corrosion refer to?

Corrosion is the natural process of a metal converting to a more chemically stable form.

What is viscosity dependent on?

Viscosity is affected by the size of particles and the attraction between those particles.

What is the difference between metals and non-metals?

Metals have free electrons that allow for conductivity, while non-metals have their electrons bound in connections.

What are the main states of matter?

The three main states of matter are solid, liquid, and gas.

How does temperature affect particle movement?

The hotter particles are, the faster they move.

What are subatomic particles?

Subatomic particles are the building blocks of atoms, including protons, neutrons, and electrons.
