Electron Theory Flashcards
The outermost shell is called the valence shell and electrons in the shell are called valence electrons. The maximum number of electrons in the valence shell is\_\_\_\_\_. a 2 B 4 C 6 D8
D 8
The attraction between the positive charge of the protons and the negative charge of electrons keeps the electrons from breaking out of there orbit. True or false
True
Because the attractive force of the protons is greater on electrons that are closest to the nucleus, electrons in the orbits farther away from the nucleus are more easily separated from their atomic structure. True or false
True
When energy is applied to the valence electrons, the energy is distributed evenly among all the valence electrons. True or false
True
Conducted materials have one, two, or three valence electrons. Elements with one valence electron, such as silver, copper, and gold, make the best electrical conductors. True or false
True
To prevent corrosion from forming on low-voltage electronic circuitry connectors, ______ plating is often placed on copper cable terminals.
A Silver
B. Gold
C aluminum
D. None of these
Gold
Insulators have 4 to 5 valence electrons. True or false
False
6 to 8
Semi conductors contain more than six valence electrons. True or false
False
Atoms strive for chemical stability, which is the condition where the valence shell is completely filled. This often accomplished by combining Atoms together to produce a compound Atom. True or false
True
Compounds can change the electrical characteristics of an individual atom. For example, the insulating aluminum oxide compound is very difficult to break and it often results in overheating of aluminum conductors at their terminals.
True
