Questions and Answers 100% Pass
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 an atom - ✔✔Shell 1=2
electrons, shell 2= 8 electrons, shell 3= 18 electrons, and shell 4 is 32 electrons
What is the maximum electron capacity of a valance shell? - ✔✔The valence shell can
hold a maximum of eight electrons
Electrons in orbit nearest the nuclear us contain———-energy than those in more
distant orbits. - ✔✔Electrons in orbit nearest the Nicolas contain less energy than those
in more distant orbits
What happens to a valance electron that has enough energy added to it? - ✔✔A valence
electron that has enough energy added to it, moves away from its Atom
What is the major factor that determines the category of a particular element? - ✔✔The
number of electrons in the valance shell of determines the element category

only one or two valence electrons
List, gold, silver, and copper in the order of the best connectivity - ✔✔Silver, copper,
gold
Why do metals that each have only one valence electron differ in their conductivity -
✔✔Metals that each have one valance electron differ in their conductivity, because of
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 randomly from one atom to
another - ✔✔The movement of atoms in materials that are conductors and the agitation
as they 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 direction? - ✔✔Applying a negative
charge to one end of the wire in a positive charge to the 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 of electron travel? - ✔✔The
affective speed of electric current is 186, 00 0 mi./s is much faster than the 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 charges of equal value - ✔✔The
potential difference between two negative charges of equal value of zero. There is no
potential difference.
What is the unit used to indicate the strength or size of the potential difference? -
✔✔The vault is the unit used to indicate the strength or size of the potential 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 electrons - ✔✔The third shell

number of electrons in the Valence shell
Which of the following best describes the relationship between an amp and a coulomb -
✔✔The number of amps is equivalent to the number of coulombs passing a given point
during one second
How is electric current produced? - ✔✔From the transfer of energy from valance
electron to valance electron because of applied charges
What prevents the electrons that orbit an atoms nucleus at high speeds from breaking
away from the nucleolus do to centrifugal force - ✔✔The attraction between the positive
nucleus in the negative electron
What is 5kV equivalent to - ✔✔5000 v
Elements without the production or movement of free electrons are considered? -

traveling randomly from one atom to another in an insulator
What is the effective speed of electric current? - ✔✔186, 00 0 mi./s
What do scientists believe causes magnetism? - ✔✔Scientists believe that magnetism
results from the spinning action of each electron on its own axis and orbiting around its
own nucleus.
Describe the pattern arrangement of the magnetic domains in non-magnetized in
magnetized materials - ✔✔The magnetic domains in a non-magnetized material,
arrange in a random pattern which causes the effects to cancel, resulting in no magnetic
field those in a magnetized material a line in the same direction which causes their
magnetic fields to add making the material magnetized
