What are the Four C’s of Diamond Value?
Carat
Color
Clarity
Cut
A dash in a Lewis structure represents what?
two electrons
The Luster or Shine of most metal is caused by movement of _____.
Electrons
The Measure of an atom’s ability to attract electrons to itself in a chemical bond is known as _____.
Electronegativity
This theory accounts for metals luster, conductivity and ductility.
Electron-Sea
What kind of bond? Oxygen and Sodium
Ionic Bond
Metals are freely sharing electrons when bonding because of this.
Low electron affinity
This bond forms when 2 or more atoms have high electron affinities.
Covalent Bond
What kind of bond? Nitrogen and Potassium
Ionic Bond
Chemical bond involve the rearranging of these to maximize stability.
Electrons
Nonmetals chemically combine to do what with their electrons?
Share
Metals tend to do what with their electrons when they bond with each other?
Lose
This rule state that atoms attain stability by having a full valence shell of electrons.
The Octet Rule
A mixture of atoms of a metal with another element where the mixture has metallic properties.
Alloy
The attraction between opposite electrical charges.
Electrostatic force
These bonded compounds contain one or more pairs of shared electrons.
Covalent
Characterized by a sharing among adjacent atoms and loose association with parent atoms.
Metallic
Atoms with fewer than this many valence electrons gain electrons when bonding.
Four
This type of bonded substance occurs as relatively hard, brittle crystals with high melting point, glassy lusters and unusual electrical properties.
Covalent
These result when atoms sharing the electrons have differing electronegativies.
Polar Covalent Bonds
He was responsible for developing 2 dimensional diagrams to show bonds between atoms.
Gilbert Lewis
This Octet Rule exception is stable with its 1 valence electron.
Hydrogen
In a Lewis Structure, the total number of electrons equals the total number of _____.
Valence Electrons
Which of the following does not exist as a diatomic element?: Hydrogen Oxygen Nitrogen Argon Flourine Chlorine Bromine Iodine
Argon
Which of these does not have to do with the Electron-Sea Theory?: Luster Ductility Conductivity Brittleness
Brittleness
Bond between two or more atoms with high electron affinity is _____.
Covalent
Because most metals have _____ they are most likely to fairly share electrons when bonding.
low electron affinity
Chemical bonds rearrange _____ to maximize stability.
electrons
The attraction between opposite forces is known as _____.
electrostatic force
What theory states that atoms attain stability by having a full shell of valence electrons?
The Octet Rule
When non-metals combine with each other, they _____ their electrons.
Share
Who is known for creating two dimensional diagrams?
Lewis
Which element is stable with only one valence electron?
Hydrogen
