Exams 1-6 People and Terms
A type of solid state of matter that. They are geometric in shape. For example salt or diamonds
Another type of solid state of matter. They do NOT have a geometric shape. For example glass or rubber.
describe an objects mass, weight, color, or, odor
describe a substances reactivity
Law of conservation of energy
The energy of an object at rest is equal to the energy of the object in motion.
The energy of an object at work or in motion
The energy of an object at rest
Both were early greek philosphers who discovered that matter is made up of tiny indestructible particles called atoms
The founder of the periodic table. He organized elements on the periodic table by their relative mass and similar properties.
In 1808 Dalton created the his Theory of atoms. He expanded Democritus and Leucippus ideas of matter. His theory still holds true today
was J.J. Thompsons successor. He created the gold foil experiment which proved Thompson's plum pudding model invalid. He proved that an atoms mass comes mostly from the nucleus.
Marie and Perrie Currie
Both were early scientist who created elements. Marie won a nobel prize for her work and had an element named after her.
The creator of the number 6.022 x 10
. We can use that number to find the number of molecules, atoms, and subparticles within a substance.
The number of the chemical symbol. It can tell us the number of protons an element has.
The number below the chemical symbol. When the atomic number is subtracted from the atomic mass the number of nuetrons can be found.
An element that is radioactive in nature. This is because the element has more or less nuetrons than protons
A unit of energy
The distance between adjacent crests
Shows the energy from long wavelengths with low energy to short wavelengths with high energy. For example from radio waves to gamma rays.
The distance a wavelength travels in one second
excitation of an electron
This is when an electron in an atom gains energy and goes up an energy level.
relaxation of an electron
When an electron in an atom loses energy and goes down an energy level.
Pauli Exclusion Principle
Orbitals may hold no more than two electrons with opposing spins
When energy between ions is strong.
One of the creators of the Bohr's model and quantum mechanical model. He stated "God does not role dice with the universe."
Another partner in creating the quantum mechanical model. He stated "Their can be a yes and no answer, and they won't contradict each other".
G. N. Lewis
The creator of Lewis Theory. He used dot structures or Lewis structure to represent molecules and compounds.
pure covalent bond
When atoms share electrons equally between each other
polar covalent bond
When atoms share electrons. Just not equally
When electrons are transferred.
The force exterted on the Earth by gravity
The law that deals with volume and temperature. It states that volume and temperature are directly porportional
equal volumes of gas, temperature, and pressure contain the same number of moles
The skin created on liquids. When atoms interact with their neighbors creating a net inward force
The resistance for liquid to flow
when a substance changes from its liquid state to gaseous state
When a substance changes from its gaseous state to its liquid state
When a substance changes directly from its solid state to gaseous state
The liquid a solute is dissolved in to form a solution
The combination of the solvent and the dissolved solute
The volume of a gas is directly porportional to the number of moles. The temperature is inversely porportional to the pressue
A measure of the concentration of the solute within a solution
Dynamic Chemical Equilibrium
The rate of the forward reaction is equal to the rate of the reverse reaction
Le Chateliers Principle
When a chemical system at equilibrium is disturbed the system shifts in the direction to minimize the disturbance.
effect of a catalyst
Provide an alternate route with a lower activation energy
energy of activation
The amount of energy required by certain substances to have a reaction
Hydrocarbons bonded only by single bonds. They are also known as saturated hydrocarbons
hydrocarbons that contain one single bond and at least one double bond between carbon atoms. They are unsaturated hydrocarbons
are hydrocarbons that contain at least one triple bond between carbon atoms.
