     Location:

Complete each statement.

    1. The physical effects related to force and motion of electrically charged particles is

    considered __Electricity_____.

    2. The atom is constructed with three main particles _Proton____, __Neutron___ and

    __Electron_____.

    3. The maximum number of atoms that can exist in the outermost valence ring is _8___.

    4. A material that contains more protons than electrons is considered having a

    _Positive___ charge.

    5. A material that contains more electrons than protons is considered having a

    _Negative__ charge.

    6. When one Coulomb of atoms creates a force of one joule this is considered as one

    __Volt__ of potential energy charge.

    7. The movement of electrons from one atom to another through a material will travel

    from the __Negative____ charged particles to the _Positive___ charged particles.

    8. The atoms with only one valence electron are most commonly used as conductors

    because the energy required to move electrons through the material is _low_____

    (high/low).

    9. The charge potential energy required to dislodge an electron in a good insulator is

    _high_____(high/low).

    10. __Voltage___ is a pressure energy force created by electrostatic charge forces.

Matching

    Match the Electricity Source with the appropriate description.

    1. ___C___ Electrochemical

    2. ___B___ Tribo-electric

    3. ___D___ Electromagnetic

    4. ___F___ Photovoltaic

    5. ___E___ Thermocouple

    6. ___A___ Piezoelectric

    A. When an object is placed under extreme pressure the mechanical forces of the

    pressure can cause electrons to be dislodged from the valence orbit and the object

    will create a positive charge.

    B. When two materials are traveling past each other one material may loose electrons

    in the process and become positively charged while the other material will gain

    electrons. This is dependent on the material types. This process is also known as

    static electricity.

    C. This process consists of two dissimilar electrodes placed into an electrolyte. The

    different materials of the electrodes will react with the electrolyte. One electrode will

    release an electron and become a positively charged particle into the electrolyte that

    will be attracted to the other electrode material.

    D. When a material is placed in a moving magnetic field the magnetic flux will cause

    electrons to be released from their valence orbital rings. This causes electric charges

    in a material.

    E. Energy causes an element or molecule of two dissimilar metals when heated to loose

    a valence electron. One material becomes positively charged and there is the

    potential to create electrons to move.

    F. When certain semi-conductive materials are placed in the presence of light the

    photons traveling at a large rate of speed 100,000 Meters/second hit the semi-

    conductor they cause the semi-conductor to release an electron causing a positive

    charge.
