What's the Matter
The two properties of used to define a state of matter.
Shape and volume.
This groups has a full outer valence shell as thus doesn't react with other elements.
Noble gases(Group 18)
Bonds in which electrons are shared are called ________ and bonds where electrons are transferred are called ____________.
Covalent, Ionic
NaF
Chemical Formula & atomic mass.
Sodium fluoride 42 a.m.u.
The count of these determines the atomic number.
Protons
The relationship between pressure and temperature of a gas.
Directly proportional.
This group of elements, of which Gold is a member, are highly variable in their oxidation numbers.
Transition metals
These ions are themselves compounds of various elements.
Polyatomic
When a covalently bonded molecule doesn't share electrons evenly it is called.
Polar.
A change in the number of electrons make an atom into this.
Ion
The relationship between pressure and volume of a gas.
Inversely proportional.
3 Traits of metals.
Solid at room temp, malleable, ductile, shiny, form positive ions
These bonds occur between transition metals and other elements.
Metallic
CO2
Type of atomic bond and type of electron pair bond.
Covalent bond and double bond.
When an atom has varying number of neutrons is is referred to as this.
Isotope
Particle movement and arrangement in crystalline solids.
Vibrating in place, regular/ordered.
3 Traits of Non-metals.
Gas at room temp, dull, powdery/brittle as solids, forms negative ions, poor conductors
3 Traits of covalent bonds.
Weak bonds, Between nonmetals only, Low boiling/metaling point, Prefixes on both, OR Gases/liquid at room temperature
Mn2O7
Name and atomic weight.
Manganese (VII) oxide
222 a.m.u.
The term for a positively charged atom _________ and a negatively charged atom ___________.
Cation and anion
This defines what it is to be in the plasma state of matter.
Stripped of electrons.
This classification of elements, of which Silicon is a member, have traits of two other groups, and are known for being excellent semiconductors.
Metalloids.
3 Traits of ionic bonds.
Strong bonds, Between metals and nonmetals, Solids at room temperature, High melting/boiling point, OR Only prefix for second element
Ammonium(NH4+) and Phosphate(PO43-)
The formula and how many of each element.
(NH4)3PO4
N=3, H=12, P=1, O=4
Correctly fill the electron shells of Cu.
