The lightest and most abundant element in the universe, with only a single electron, making up approximately 75% of its elemental mass 

What is hydrogen?

200

The process by which liquid turns directly into a gas

What is evaporation?

200

The subatomic particles that comprise the nucleus of an atom.

What are protons and neutrons?

200

Various forms of energy emitted or transmitted in waves or particles.

What is radiation?

200

Solid form of CO2 that cannot take liquid form unless subjected to a high level of pressure.

What is Dry Ice?

400

This element that is essential for most life on Earth and makes up about 21% of Earth’s atmosphere.

What is Oxygen?

400

The change in state where a compound goes from a gas to a liquid.

Condensation

400

The type of electrons that are found in the outer most shell of an element.

What are valence electrons?

400

The process by which unstable atomic nuclei lose energy by emitting radiation. This decay occurs when an atom's nucleus is unstable, resulting in the release of particles or electromagnetic waves.

What is radioactivity?

400

The most brash, strong and conductive element category that can be found on the periodic table.

What are metals?

600

The only metal that is liquid at room temperature

What is Mercury?

600
The process where a solid goes directly to a gas.
What is sublimation?
600

These are atoms of the same element that have different numbers of neutrons.

What are isotopes?

600

Born on November 7, 1867, in Warsaw, Poland, this pioneering physicist and chemist was renowned for groundbreaking research on and discovery of radioactivity, radon and polonium.

Who is Madam Curie?

600

The process by which chemical bonds are formed, broken or both to form new compounds.

What is a chemical reaction?

800

This natually occurring metal is known for its high melting point, this element is commonly used in light bulb filaments

What is Tungsten?

800

A state of matter with unique properties due to its high energy level.  Atoms of compounds begin to lose their electrons.

What is plasma?

800

This number represents the total number of protons and neutrons in an atom's nucleus.

What is the atomic mass?

800

The most radioactive element on the periodic table due to it's highly unstable and has a very short half-life

What is Francium?

800

The law of thermodynamics that states that energy and matter cannot be created or destroyed, but simply transformed or rearranged into new forms.

What are the laws of conservation of energy and matter?

1000

This radioactive noble gas is colorless, odorless, and can be a health hazard if it accumulates indoors.

What is Radon?

1000

The process in which a gas changes directly into a solid bypassing the liquid phase.

What is deposition?

1000

Subatomic particles that are often more abundant in larger and heavier elements.

What are neutrons?

1000

Physicist best known for the pioneering work in the study of radioactivity, which led to the discovery of the phenomenon in 1896. Research focused particularly on uranium salts, and that they emitted rays capable of penetrating opaque materials.
