Chemistry and Matter
The study of mass and the changes it undergoes.
What is chemistry?
This element has a mass of 20 and an atomic number of 10.
What is neon?
Vistence shell electron pair repulsion.
What does VESPR stand for?
Breaking apart of a chemical compound into 2 or more elements.
What is the definition of decomposition?
What are pipettes?
This is made up of atoms and it also takes up space.
What is matter?
A bunch of atoms or only one atom where the number of electrons are not the same.
What is an ion?
What is the naming for NaOh?
2NA + Cl2 = 2NaCl is an example of this type of reaction.
We use this concept to find mass or volume
How do we use density?
One of these words is how close the measures are to each other. The second word is how close the measures are to what is expected.
What is accuracy and precision?
Who is J.J. Thompson?
Ag(3)PO(4)
What is the formula for silver phosphate?
This piece of chemistry that studies numbers of materials that are involved in reactions.
What is the definition of stoichiometry?
You should wear these when working with chemicals in a lab.
What are googles?
It could break down into mixtures and pure substances. It could break down into solids, liquids, or gases.
How is matter described?
1s (1) 2S(2)2P (6) 3S (1)
What is the electron configuration of sodium?
C
What is the dot structure for carbon?
These materials are used to lead the chemical reaction. They are on the left side of the equation.
These will have the same number of electrons and protons but will have a different number of neutrons.
What are isotopes?
Distillation, filtration, and evaporation are examples of this.
How is matter separated?
A chemical element that has similar chemical properties which has different masses but the same atomic numbers.
What is an isotope?
These are chemicals that break apart to make hydrogen ions.
What do acids do?
A pure substance made of 2 or more elements which are chemically put together.
What is a compound?
Metallic character and ionization energy are examples of these.
What are periodic trends?
