Chapter 2 Flashcards
The molecules found in a pane of glass can be best described as:
Amorphous solid, having short range order
A partial charge resulting from an uneven distribution of electrons around and atom forms a bond known as
Secondary
What type of bond is formed when electrons are shared by all the atoms that make up that object and may be thought of as positive cores in a cloud of negative mobile valence electrons?
Metallic
A notable advantage of using ceramic materials in dentistry is the property of
Translucency
A dental polymer with many cross-links as compared to one with no cross-links would be a dental material that is
Stiff and strong
All of the following are examples of a composite except
Tin foil
When does shared electrons of a covalent bonds are not shared equally, and the one of the bonded Adams is partially positive and the other is partially negative, a ————- is formed
Permanent diploe
The sliding of atoms Past each other allows them this material to bend, not fracture, and maintain its strength. This material is an example of a
Metal
A mixture of two liquids that do not band together to form one liquid is termed an
Emulsion
When two atoms share a pair of electrons, the resulting atomic bomb and is termed
Covalent Bond
