  1. Question 1

    What is electronegativity?

    • AThe ability of an atom to attract shared electrons
    • BThe ability of an atom to lose protons
    • CThe number of neutrons in an atom
    • DThe total number of electron shells
    Show answer

    Answer: A

    Electronegativity is an atom's ability to attract shared electrons in a chemical bond.

  2. Question 2

    Which type of covalent bond forms when electrons are shared equally?

    • APolar covalent bond
    • BIonic bond
    • CNon-polar covalent bond
    • DCoordinate covalent bond
    Show answer

    Answer: C

    Equal sharing of electrons produces a non-polar covalent bond.

  3. Question 3

    Which type of bond involves unequal sharing of electrons?

    • AMetallic bond
    • BPolar covalent bond
    • CNon-polar covalent bond
    • DIonic bond
    Show answer

    Answer: B

    A polar covalent bond involves unequal sharing of the bonding electrons.

  4. Question 4

    Which molecule contains a non-polar covalent bond between identical atoms?

    • AHCl
    • BH2O
    • CCl2
    • DNH3
    Show answer

    Answer: C

    The identical chlorine atoms share bonding electrons equally in Cl2.

  5. Question 5

    Which molecule has a polar covalent bond between its atoms?

    • ACl2
    • BN2
    • CH2
    • DHCl
    Show answer

    Answer: D

    Chlorine attracts the shared electrons more strongly than hydrogen in HCl.
