ABYC CORROSION EXAM 2026 BOAT
ELECTRICAL SAFETY WORKBOOK SOLVED
QUESTIONS COMPILATION
◉ Define Ionization
Answer: The process by which an atom or molecule acquires a
charge.
◉ What are the two types of chemical bonds?
Answer: Covalent and ionic
◉ In covalent bonds, atoms form chemical bonds by _______ electrons.
Answer: Sharing.
E.g. water, H2O
◉ In ionic bonds, atoms form chemical bonds by _______ electrons.
Answer: Giving up or gaining electrons.
The atom giving an electron become a positive ion. The atom gaining
an electron becomes a negative ion. Oppositely charged bodies are
attracted to each other, bonding them together.
,E.g. Sodium Chloride, NaCl, table salt.
◉ T/F Atoms in the valence shell are involved in the corrosion
process?
Answer: True
◉ What is disassociation with regard to electrolyte?
Answer: When an ionic substance (like sodium chloride, table salt) is
immersed in water it disassociates, or separates, into positive and
negative ions.
◉ __________ are electrical conductors in which current is carried by
ions rather than by free electrons.
Answer: Electrolytes
◉ The three categories of corrosion are:
Answer: Electrochemical, galvanic, and electrolytic
◉ Single-metal corrosion is technically referred to as
Answer: Electrochemical corrosion
◉ Electrochemical corrosion is commonly known as
, Answer: Single-metal corrosion
◉ Galvanic corrosion is sometimes referred to as
Answer: Two-metal corrosion or bi-metallic corrosion
◉ Corrosion is often improperly called
Answer: Electrolysis.
Electrolysis is what happens to the electrolyte not the metals
involved.
◉ ____________ is the destructive alteration of metal by reachtion with
its environment.
Answer: Corrosion
◉ When a metal is less noble it is referred to as
Answer: Anodic
◉ T/F Anodic metals are least active and are resistant to corrosion
Answer: False.
Anodic metals are most active and corrode more easily.
