The Study of Matter
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?
This is the least massive part of the atom.
What is an electron?
The vertical columns of the periodic table are called these.
What are groups?
These are atoms of two or more different elements that are chemically bonded.
What are compounds?
You use this to convert from grams to moles or moles to grams.
What is the molar mass?
These parts of the atom make up the nucleus.
What are protons and neutrons?
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?
These types of elements are above the stairs on the right side of the periodic table.
What are non-metals?
This state of matter has a definite volume, but not a definite shape.
What is liquid?

This instrument is used in the lab to measure mass.
What is a triple beam balance?
This law states that matter is neither created nor destroyed.
What is the Law of Conservation of mass (matter)?
These are the electrons that are the furthest from the nucleus.
What are Valence electrons?
These are the horizontal rows of the periodic table.
What are periods?
These types of mixtures, like oil and water, are not evenly mixed.
What are heterogeneous mixtures?
The number of significant figures in the following number: 100.000
What is 6?
These atoms have the same atomic number but different mass numbers much like fat twins.
What are isotopes?
The number of electrons in the following electron configuration: 1s22s22p63s23p5
What is 17?
This is the name of the group 18 elements that are not reactive.
What are noble gases?
This type of property can only be observed without changing the substance such as color or mass.
What is a physical property?
The mass of an object divided by its volume.
What is density?
This is the value for Avagadro's Number
What is 6.022 x 1023
This type of subshell (orbital) is the shape of dumbbells.
What is the p orbital?
These types of metals include groups 3-12 on the periodic table.
What are transition metals?
