100
The distance between the crests of an electromagnetic wave.
What is wavelength?
100
The amount of time it takes 50% of a radioactive isotope to decay.
What is half-life?
100
This state of matter contains loose particles that conform to their surroundings.
What is liquid?

6.022*10^23
How many molecules are in a mole?
100
In this type of reaction, one element replaces another element in a compound. Example: Fe + 2HCl --> FeCl2 + H2
What is single replacement?
200
Energy that propagates through space, with two distinct fields, which travel at 90 degree angles to each-other.
What is electromagnetic radiation?
200
The type of radiation emitted from the nucleus that are also known as Alpha particles.
What is Helium-4?
200
These forces hold atoms together into molecules.
What are intramolecular forces?
200
This diatomic salt molecule has a molar mass of 74.5513 grams.
What is KCl? (potassium chloride)
200
It is written as ΔH, and it measures the change in energy after a reaction.
What is enthalpy?
300
Electromagnetic radiation with wavelengths between 400 and 700 nanometers.
What is the visible spectrum?
300
The type of radiation emitted from the nucleus when a proton converts into a neutron.
What is positron emission?
300
This special intermolecular force takes advantage of small, highly electronegative elements, such as Fluorine.
What is a hydrogen bond?
300
The number of moles in 916.5kg of Zircon, a mineral with the chemical formula ZrSiO4.
What is 5000?
300
It is the type of energy change seen in the this equation: N2(g) + O2(g) → 2NO(g); ΔH = +180.5 kJ
What is an endothermic reaction?
400
Electromagnetic radiation with wavelengths above 1000 meters.
What are radio waves?
400
Common among lower mass elements, this nuclear process combines the nucleus of smaller elements into one, larger element.
What is Nuclear Fusion?
400
This intermolecular force is between an ionic molecule and a polar molecule.
What is Ion-Dipole attraction?
400

500
This orbital is responsible for creating different colors, when a molecule has a metal in its center.
What is the d orbital?
500
Common among larger mass elements, this nuclear process splits apart it's nucleus, releasing neutrons, triggering a chain reaction event.
What is Nuclear Fission?
500
This phase change of matter is characterized by the conversion of a solid directly into a gas.
What is sublimation?
500
The number of molecules in 10 grams of Iron.
