The study of matter and its changes.
What is Chemistry?
This SI unit for length is a measure of distance.
What is the meter?
This is the smallest form of matter.
What is an atom?
According to this Albert Einstein equation mass can be converted into energy and energy to mass.
What is E=mc2?
This is the length between adjacent waves.
What is wavelength?
These are atoms of two or more different elements that are chemically bonded.
What are compounds?
This "if-then" statement is a testable explanation of observed data.
What is a hypothesis?
These parts of the atom make up the nucleus.
What are protons and neutrons?
Nucleons are made of ______ and _________.
What are neutrons and protons?
This 3-D region around the nucleus indicates the probable location of an electron. The space the electron can go into.
What is an orbital?
This state of matter is composed of atoms that have lost many of their electrons.
What is plasma?
The mass of an object divided by its volume.
What is density?
This law states that matter is neither created nor destroyed.
What is the Law of Conservation of mass (matter)?
When something is this it is releasing energy during nuclear decay.

What is delta?
This element has a noble gas configuration of [Ne]3s23p4.
What is sulfur?
Solubility, how something will dissolve is considered this type of property.
What is a physical property?
This process is where you write what the problem gave you, draw the multiplication sign, draw the line, and put the unit you want on the top and the unit you want to get rid of on the bottom.
What is dimensional analysis?
This is the value of Avagadro's number.
What is 6.022 x 1023?
Where smaller, relatively stable, nuclei are forced together to create a larger nucleus with the release of binding energy.
