The name for mixtures like salads, trail mix, oil and water, etc.

What is heterogeneous?

100

The term we use for average kinetic energy

What is temperature?

100

The subatomic particle that determines the identity of the atom

What is a proton?

100

The type of decay resulting from losing a helium nucleus

100
A typically inert group of elements on the periodic table.

What are the Noble Gases?

200

3 is the number of them for this quantity: 0.00500

What are significant figures?

200

Heat tends to move from an area of greater molecular movement to slower molecular movement until it reaches this state.

What is equilibrium?

200

The subatomic particle that determines the reactivity of an atom.

What is an electron?

200

This type of decay would allow the element to remain the same while releasing a large amount of energy.

What is gamma decay?

200

This group on the periodic table has 7 valence electrons and is extremely reactive.

What are the halogens?

300

The color yellow on the NFPA safety diamond.

What is the reactivity section?

300

The law we use to quantify the relationship between volume and temperature.

What is Charles Law?

300

The term used to describe an atom that has more electrons than protons.

What is an anion?

300

The process of using isotopes to determine the age of different objects.

What is radioisotope or carbon dating?

300

This group on the periodic table are semi-conductive, sometimes brittle/malleable, and have varying properties.

What are metaloids?

400

The third planet from the sun.

What is Earth?

400

The law we use to quantify the relationship between number of moles and volume.

What is avogadro's law?

400

The term used to differentiate between the same element with different masses.

What is an isotope?

400

The type of decay that emits an electron and changes a neutron in the parent isotope to a proton.

What is beta decay?
400

How the periodic table is organized

What are periods and groups based on trends and properties (like the alien periodic table)

500

The term for a mathematical relationship where when one quantity increases the other decreases (and vice versa). 

What is inverse?

500

Gas molecules tend to have these types of collisions, meaning that when they hit each other they bounce off completely conserving energy.

What is elastic? 

500

How you determine the number of neutrons in an atom.

What is taking the mass and subtracting the atomic number?

500

This quality increases as frequency increases.

What is energy?

500

The leading architect behind the modern periodic table we use today.
