Atomic History
What does the atomic theory state ^_^
That atoms make up everything
How does nuclear attraction "trend"?
Up and to the right
What is the oxidation state of Oxygen ,3.
-2 most times, (bonus points) -1 in peroxides p0p
What is stronger, Intramolecular forces of Intermolecular forces?
Intramolecular forces
What are some characteristics of Francium (very bottom left of the table).
Big atomic radius, high metallic character, low electronegativity, low ionization energy, low nuclear attraction, and low electron shielding.
Who made the Plum pudding model ;)
J.J Thompson :8
How does metallic character "trend"?
Down and to the left
What is the oxidation states: F3O-6
O: -2
F: -1
F3:-3
If 2 H atoms forms a covalent bond, is this a polar or non-polar bond?
Non-polar :D
______________ forces include covalent bonds, ionic bonds, and metallic bonds. While ______________ forces include dipole - dipole interactions, hydrogen bonds, and london dispersion forces.
Intramolecular, intermolecular. <.>
When did Democritus propose his idea that the world is made of invisible particles call atoms :0
400 B.C.E
How does atomic radius "trend"?
Down and to the left
What is the oxidation state of Hydrogen ?-?
1 mostly, -1 with metals :L
What is a polar covalent bond ?
A covalent bond that unevenly shares electrons (because of uneven electronegativity) U-U
What is the charge of 1 AU: H4F3O3Au5-3
+2
Who was able to recognize the idea of a nucleus through his gold foil experiment?
Ernest Rutherford :3
How does electron shielding "trend"?
Up and to the right
What is the oxidation state of all the elements: O3K
O: -2
O3:-6
K: 6
Where do Intramolecular forces act :}
In a single molecule :>
What does AMU stand for :0
Atomic Mass Unit
John Dalton proposed atoms cannot what :3
Be divided
How do both electronegativity and ionization energy "trend"?
Up and to the right *o*
In the context of redox reactions, what does reduction mean? ,0,
To gain electrons ;3
When a non-polar atom becomes a temporary dipole because electrons are unevenly spread within, it is called:
London Dispersion Forces .<.
What are Hydrogen Bonds?
These intermolecular bonds are always a type of dipole - dipole interactions. These occur only when partially positive Hydrogen atoms a partially negative electronegative atom (such as oxygen, nitrogen, or fluorine) come together to form a compound.
