Why do only the outer electrons leave their orbit shells? Only outer electrons leave their orbit shells, because electrons furthest from the
nuclear us are more easily freed from their orbits due to a weaker electrostatic
force
What is required to have a balanced atom? The number of electrons must equal the number of protons to have a balanced
atom
List the capacity for each of the first for orbital shells of Shell 1=2 electrons, shell 2= 8 electrons, shell 3= 18 electrons, and shell 4 is 32
an atom electrons
What is the maximum electron capacity of a valance The valence shell can hold a maximum of eight electrons
shell?
Electrons in orbit nearest the nuclear us contain———- Electrons in orbit nearest the Nicolas contain less energy than those in more
energy than those in more distant orbits. distant orbits
What happens to a valance electron that has enough A valence electron that has enough energy added to it, moves away from its Atom
energy added to it?
What is the major factor that determines the category of The number of electrons in the valance shell of determines the element category

conductor?
List, gold, silver, and copper in the order of the best Silver, copper, gold
connectivity
Why do metals that each have only one valence electron Metals that each have one valance electron differ in their conductivity, because of
differ in their conductivity the way their atoms pack together into a solid structure
Describe the two characteristics of an insulator The two characteristics of an insulator are its valence Shell is almost filled and
tends to be fairly stable and two it, tries to finish, filling its valance shell by
capturing additional free electrons.
How many valence electrons are in a semiconductor A semiconductor has four valence electrons.
Name of the two types of electron current flow Random drift and directed. Flow are the two types of electron current flow.
, What causes electrons to be knocked loose and travel The movement of atoms in materials that are conductors and the agitation as they
randomly from one atom to another collide cause electrons to be knocked loose and travel randomly from one atom
to another
What can force electrons to all move in the same Applying a negative charge to one end of the wire in a positive charge to the
direction? other can force electrons to all move in the same direction
What actually produces electric current? The transfer of energy from valence electron to valance electron as a result of
applied charges is what actually produces electric current
How does the speed of electric current compared to that The affective speed of electric current is 186, 00 0 mi./s is much faster than the
of electron travel? actual speed of electron travel
What is the basic measurement unit of electron current? The ampere is the basic measurement unit for electron current
Define electromotive force (EMF) EMF is the electrical force that motivates electrons to move in a wire
What does the term potential difference mean? Potential difference is the algebraic difference between the electrical individual
potential's of two points
What is the potential difference between two negative The potential difference between two negative charges of equal value of zero.
charges of equal value There is no potential difference.
What is the unit used to indicate the strength or size of The vault is the unit used to indicate the strength or size of the potential
the potential difference? difference
Define a volt in terms of current and resistance. 1 V is the amount of force required to produce a current of one amp through a
resistance of one ohm
What are three alternate ways to Express five and 3MA 5 microvolts, 5/1000000 volts or 0.00005 V, and three Milla amps. 3/1000 amps or
0.003 A
What are two alternate ways to express 2 megavolt? 2MV or 2 million volts
What are two alternate ways to express for kilovolts? 4kv or 4000 volts
Which orbital shell has a maximum electron capacity of 18 The third shell
electrons
Why are semiconductor material is not good conductors The valance shells are only half filled
nor good insulators

Which of the following best describes the relationship The number of amps is equivalent to the number of coulombs passing a given
between an amp and a coulomb point during one second
