    Complete the following sentence:There are two types of electron: core electrons and ______ (outside) electrons.

    Explanation
    Valence electrons are the electrons located in the outermost energy level of an atom. These electrons are involved in chemical bonding and determine the reactivity and chemical properties of an element. Core electrons, on the other hand, are the electrons located in the inner energy levels of an atom and are not involved in bonding. Therefore, the correct answer to complete the sentence is "valence," as it accurately describes the type of electrons found outside the core.

    Which of the following is true for the values of electronegativity?

    • If the difference in values is greater than 1.7, the bond is more likely to be ionic

    • If the difference in values is greater than 1.7, the bond is more likely to be covalent

    • If the difference in values is less than 1.7, the bond is more likely to be ionic

    Correct Answer
    A. If the difference in values is greater than 1.7, the bond is more likely to be ionic
    Explanation
    If the difference in electronegativity values between two atoms is greater than 1.7, it indicates a large difference in their ability to attract electrons. This suggests that one atom will have a much stronger pull on the shared electrons, resulting in an unequal sharing of electrons and the formation of an ionic bond. Ionic bonds occur between atoms with significantly different electronegativity values, leading to the transfer of electrons from one atom to another to achieve a stable electron configuration.

    Complete the following sentence:Ionic bonding involves the formation of ions through the loss or gain of #_________#.The two ions are held together by #__________# forces.

    Correct Answer
    Electrons
    Electrostatic
    Explanation
    Ionic bonding involves the formation of ions through the loss or gain of electrons. The two ions are held together by electrostatic forces.

    Why don't nobel gases bond?

    • Filled s and p orbitals in outer shell

    • All orbitals in outer shell filled

    • Filled d and f orbitals in outer shell

    Correct Answer
    A. Filled s and p orbitals in outer shell
    Explanation
    Noble gases do not bond because their outermost energy level, or shell, is completely filled with electrons. Specifically, the s and p orbitals in the outer shell are filled with electrons. This complete electron configuration provides noble gases with a stable and low-energy state, making them highly unreactive and unlikely to form chemical bonds with other elements.
