    An _____________ bond is formed between a metal and a nonmetal each with opposite charges.

    Explanation
    An ionic bond is formed between a metal and a nonmetal when they have opposite charges. In an ionic bond, the metal atom loses electrons to become a positively charged ion, while the nonmetal atom gains those electrons to become a negatively charged ion. The attraction between these opposite charges forms the ionic bond. This type of bond is characterized by the transfer of electrons from one atom to another, resulting in the formation of a crystal lattice structure.

    A positively charged particle is called a/an _____________.

    Explanation
    A positively charged particle is called a cation because it has lost one or more electrons, resulting in a net positive charge. Cations are formed when atoms or molecules lose electrons, leaving behind a greater number of protons than electrons. This imbalance in charge creates a positive charge, making the particle a cation.

    A negatively charged ion is called a/an _________________.

    Explanation
    A negatively charged ion is called an anion because it has gained one or more electrons, resulting in an overall negative charge. Anions are attracted to positively charged ions (cations) and are commonly found in ionic compounds.

    The ________ rule states that atoms tend to combine in a way that their valence shells have eight electrons.

    Explanation
    The octet rule is a principle in chemistry that states that atoms tend to combine in a way that their valence shells have eight electrons. This is because having eight electrons in the valence shell makes the atom more stable, similar to the electron configuration of noble gases. By sharing, gaining, or losing electrons, atoms can achieve this stable configuration and form chemical bonds with other atoms. The octet rule helps explain the formation of compounds and the behavior of elements in chemical reactions.

    Single, double, and triple bonds are examples of ______________ bonds.

    Explanation
    Single, double, and triple bonds are examples of covalent bonds. Covalent bonds occur when two atoms share electrons in order to achieve a stable electron configuration. In a single bond, two atoms share one pair of electrons, in a double bond they share two pairs of electrons, and in a triple bond they share three pairs of electrons. These types of bonds are typically formed between nonmetals and are characterized by their strong bond strength and localized electron density between the atoms involved.

    An atom with eight valence electrons in its outermost energy shell is considered ____________.

    Explanation
    An atom with eight valence electrons in its outermost energy shell is considered stable because it has achieved a full octet, which is the ideal electron configuration for many elements. A full octet corresponds to a stable electron configuration similar to the noble gases, which have complete outer energy shells. This stability is important because it minimizes the atom's tendency to gain or lose electrons in order to achieve a more stable electron configuration.

    _______ bonds intersect orbitals in two distinct places and are usually weaker than sigma bonds.

    Explanation
    Pi bonds are formed when two p orbitals overlap sideways, resulting in the formation of a bond that is located above and below the plane of the bonded atoms. Unlike sigma bonds, which are formed by the head-on overlap of orbitals, pi bonds are weaker because the sideways overlap is less effective in holding the atoms together. Therefore, pi bonds intersect orbitals in two distinct places and are usually weaker than sigma bonds.

    A _______ bond is another name for a single covalent bond and is the strongest type.

    Explanation
    A sigma bond is another name for a single covalent bond and is the strongest type. In a sigma bond, the electron density is concentrated along the internuclear axis, resulting in a strong overlap of atomic orbitals. This type of bond allows for the sharing of electrons between two atoms, creating a strong and stable bond.

    The force that holds two ions together is called ___________________.

    Explanation
    The force that holds two ions together is called electrostatic attraction. This refers to the attraction between oppositely charged ions, where one ion has a positive charge and the other has a negative charge. This force is due to the electrostatic interaction between the charged particles and is responsible for the stability of ionic compounds.
