Chemistry
What are the 5 states of matter?
solid, liquid, gas, plasma, and BEC
What are signs of physical changes?
The color, odor, texture, shape...
(anything you can detect with your senses)
What are the subatomic particles
protons, neutrons, electrons
Periods vs. groups
Groups (18) columns
Periods (7) rows
What is an Ion?
different versions of an element with
1)different # of e- 2) different charge
What does BEC stand for?
Bose Einstein Condensate
What are signs of a chemical change?
Reactivity, Flammability, producing new substances
What does a Bohr diagram look like?
a Bohr diagram is in the form of a planetary model
Families vs. Classes
Families: groups
Classes: periods
Cation vs. Anion
Cation = positively charged (loses e-)
Anion = negatively charged (gains e-)
What is a solid's particle behavior?
Very slow
What does boiling mean?
a liquid is turning into a gas
What is a Lewis structure?
it's a structure that shows the valance electrons-
How many families are there?
9
What is Oxidation?
the change in the # of e- from the normal atom to the ion
What is the order of coldest to hottest the BEC temp chart?
BEC > Solid > Liquid > Gas > Plasma
What does freezing mean?
a liquid into a solid
What is the Octet rule?
For elements with 2 or 3 orbitals need at least 8 e-
What does BCNO stand for?
Boron, carbon, nitrogen, oxygen
What are the charges?
(+) if the e-s were lost
(-) if the e-s were ganed
What is a liquid's particle behavior?
Medium
what does melting mean?
solid into a liquid
This many electrons can be on how many orbitals?
2 = 8e- 3 = 18e-
What is the smallest family?
Bonus Question: What is any Isotope?
same elements with a different # of n and therefore, a different mass
