Shiny, metallic, conduct heat well and electric currents into solid form
Metals
atoms of the same element with different masses
Isotop is also
Quantitative description that has a unit and number.
What is a value?
understand core concepts;simplified reality
Model
Constant volume, variable shape, faster than solid
Liquid
Link between 2 atoms due to the sharing of two electrons 2 nonmetallic elements
Covalent Bond
amount of matter in an object
Mass
H, O, N, F, Ci
Noble Gases
structure and behavior of matter
What is Chemistry?
Gold Au can be hammered into sheets without breaking
Malleable
charged particles due to a loss or gain of electrons
Ions
anything that occupies space
Matter
Earth its the measure of the force of gravitational attraction between the object and Earth
Weight
a=mass number which is on the bottom in periodic table and is protons + neutrons; Z is Atomic
#,can vary & is # of protons
A^Z X
particles lose 1 or more electrons leaving them with a positive overall charge
Cation
Freedom of motion of their particles and how strongly the particles attract
How do solids, liquids, and gases differ?
particles gain one or more electrons leaving them with a negative overall charge
Anion
atoms with same atomic # but different mass #, atoms with same # of protons & electrons in
uncharged atom but different # of neutrons,
Isotopes
constant shape and volume, always moving direction and velocity vary
Solid
114+ building block of matter, cannot be chemically converted into simplar substance
Elements
All matter is composed of particles and all particles are in motion (varying speeds)
Kinetic Molecular Theory
Electrons share equally there is an even distribution of the - charge for the electrons in the
bond no partial charges of atom
Non-polar Covalent
Variable shape and volume, large avg. distance between particles little attraction
Gas
Neuron= 0 charge Proton= +1 p+ Electron= -1 charge
Neuron, proton, electron
No=Mixture Yes-can it be with a single symbol Yes- Element H2 no=compound H20
Classify Matter-Constant Comp, chemical formula to describe?
