  1. Question 1

    What happens when metals lose electrons?

    • AThey form positive ions
    • BThey form negative ions
    • CThey form neutrons
    • DThey lose their nuclei
    Show answer

    Answer: A

    Metals generally lose electrons and form positive ions called cations.

  2. Question 2

    What is metallic character?

    • AThe tendency of an element to gain neutrons
    • BThe tendency of an element to lose electrons
    • CThe tendency of an element to gain protons
    • DThe tendency of an element to form gases
    Show answer

    Answer: B

    Metallic character describes the tendency of an element to lose electrons and form positive ions.

  3. Question 3

    How does metallic character generally change down a group?

    • AIt decreases
    • BIt remains constant
    • CIt increases
    • DIt becomes zero
    Show answer

    Answer: C

    Metallic character generally increases down a group because atoms become more able to lose their outermost electrons.

  4. Question 4

    How does metallic character generally change from left to right across a period?

    • AIt increases
    • BIt decreases
    • CIt remains constant
    • DIt becomes zero
    Show answer

    Answer: B

    Metallic character generally decreases from left to right across a period.

  5. Question 5

    Which region of the periodic table generally contains the most metallic elements?

    • ATop right
    • BBottom left
    • CTop left
    • DBottom right
    Show answer

    Answer: B

    Metallic character is greatest toward the bottom left of the periodic table.
