Chemistry
What are the 5 states of matter?
Solid, Liquid, Gas, Plasma, B.E.C
What are Physical properties of matter?
You can detect them with your senses
(odor, texture, color, size...ect.)
(reversible)
What does a Bohr diagram look like?
A planetary model
Periods vs. Groups
Periods [18]= (rows)
Groups [7] = (columns)
What is an Ion?
different versions of an element with a different # of e- and different charge
What is a solid's particle behavior?
Very slow
What are the chemical properties of matter?
reactivity, flammability, produce new substances
(irreversible)
What is a Valance e-?
an element's position within a specific group
Families vs. Classes
Families = groups
Classes = periods
What might atoms need to do in order to be stable?
gain or lose e-
What is a liquid's particle behavior?
in the middle (medium)
What does boiling mean?
liquid into gas
What is the Octet rule?
2 or 3 orbitals need at least 8 e-s
How many families are there?
9
If an atom gains e-...
It's charge will be negative
What are the changes in the states of matter?
melting, freezing, vaporization, condensation, sublimation, deposition, ionization, deionization
What does melting mean?
a solid turned to liquid
What are the Subatomic particles?
P (protons+) E (electrons-) N (neutrons=)
Name them (the families):
Alkali metals, Alkaline earth metals, Transitions, BCNO, Lanthanides, Actinides, Halogens, Noble gasses, Hydrogen
If an atom loses e-...
The charge will be positive
What is plasma's particle behavior?
Crazy (chaotic)
What does freezing mean?
liquid into solid
What is a Lewis structure?
uses an element's symbol with dots representing its valence electrons
What is the smallest family?
the Hydrogen family
What do you call a positively charged ion?
a Cat-ion
