Chrysopoeia
5ve, N is the most abundant atomospheric element, 0.06g As = lethal, Sb was used in Egypt for eye makeup
Rutherfords Model
English physicist, 1897, cathode ray tube --- discovered that the cathode ray was made up of negatively charged particles...electrons
AlkYne (sp)
The ability of an electron to behave like a particle and a wave simutaneously
5A - Prictogens
3ve-, Aluminum is the 3rd most abundant element in the Earth's crust
Linus Pauling
7ve, Fluorine based acids, can dissolve glass
Covalent Bonding
English physicist, 1932, *student of Rutherfords, found that deflected particles gained mass that had no charge, neutron
Democritus
6ve, O is the most abundant crystal element, All hydrogen-cholcogen compounds are toxic, except water
John Dalton
Triple/single, 2 pi bonds and sigma bonds, complex (1:1 ratio)
Eugen Goldstein
A universal cure
Sir Antoine Laurent de Lavoisier
4ve-, Diamonds are pure carbon, Silicon is the 2nd most abundant crystal element
Elixer of immorality
Greek philosopher, 460-370 B.C. , coined the term "atomos" (uncuttable)
7A - Halogens
Jewish Physicist, 1886, Canal Ray -- found rays traveling opposite of the cathode ray... Containing protons (p+).
Both Ionic and Covalent
Sharing of e-, tend to be liquid/gases, lower melting and boiling points, insulators, molecule
Max Planck
English Chemist/teacher, 1766-1864, Atomic theory
Alkahest
Both involve ve-, Both achieve a fake Noble Gas e- configuration
Gilbert Lewis
Find a way to live forever
Erwin Schrodinger
A universal solvent
Superposition
U.S. physicist, 1868-1953, Oil drop experiment, discovered the charge of the electron to be 1.60 x 10 ^-19 coulombs-- mass of electrons 1/1,840 H
1A - Alkali Earth Metals
All matter is made of atoms, all atoms of the same element are the same, atoms of different elements can physically mix in whole # ratios, when atoms mix/seperate --chemical reaction occurs
2A - Alkaline Earth Metals
German physicist, 1858-1947, E=hV
Panaceas
1913, Danish physicist, *student of Rutherfords
4A - Crystallogens
8ve...except He, inhert (nonreactive), He is the 2nd most abundant element in the universe
Ernest Rutherford
Transfer of e-, Crystalline Solids, High Melting and boiling points, dissociate ...free ions...conduct electricity, compound
Ionic Bonding
Transmutation of base metals into gold
AlkEne (sp2)
1913, Lewis Dot Diagrams
8A - Noble Gas
Have lve- (outermost), highly reactive with water
J.J. Thompson
French alchemist, "The Father of Modern Chemistry", transformed alchemy into a quantitative field
Robert Millikan
All single bonds, all sigma, simplest, ( 1:4 ratio)
Niel Bohr
Double/single, pi and sigma, (1:2 ratio)
AlkAne (sp3)
1869, Russian Chemist/teacher, He organized the elements by mass (we organize by atomic number), "The Father of the Modern Periodic Table"
Atomic theory
Simple, could not explain certain properties (metals changing color when heated
James Chadwick
Austrian physicist/mathematician, 1887-1961, Schrodingers Cat (thought experiment)
3A - Icosagens
Electronegativity, Pauling units/ electron volts
Dimitri Merdeleev
New Zealand Physicist, 1908-1911, Gold foil experiment, *student of J.J. Thompson's, discovered that atoms are mostly empty space... With dense center (nucleus) containing protons;
6A - Chalcogens
2ve-, less reactive with water, Radium is radioactive and was used to make glow in the dark paint
