Braineos2

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?

M 10^6

Mega

understand core concepts;simplified reality

Model

Constant volume, variable shape, faster than solid

Liquid

Liquid

Hg + Br

Link between 2 atoms due to the sharing of two electrons 2 nonmetallic elements

Covalent Bond

m 10^-3

Milli

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

c 10^-2

Centi

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

c-0-100

Celcius

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

0 K lowest point

Kelvin

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

32 and 212

Farenheight

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?

u 10^-6

Micro

k 10^3

Kilo
