About This Quiz


Do you know any vocabulary related to chemistry? Some examples include the two types of bonds, which are ionic bonds and covalent bonds. Electrons are negatively charged particles; bond energy is the amount of energy required to break one mole of chemical bonds. The chemical property is a property that can only be observed when a chemical change occurs. This chemistry exam quwestion trivia will help you have a better understanding of chemistry. Don’t forget to take your certificate at the end of the quiz.

    A ________ bond is formed when three electron pairs are shared between two atoms.

    Explanation
    A triple bond is formed when three electron pairs are shared between two atoms. In a triple bond, two atoms share three pairs of electrons, resulting in a strong and stable bond. This type of bond is typically found between carbon atoms in molecules such as acetylene (C2H2) and nitrogen atoms in molecules such as nitrogen gas (N2). Triple bonds are characterized by their high bond energy and short bond length, making them stronger and more rigid than single or double bonds.

    Molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain ________ electrons.

    Explanation
    Molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons. This is because having eight electrons in the outermost shell, also known as the octet rule, allows the atoms to achieve a stable electron configuration similar to the noble gases. This stability is achieved through the sharing, gaining, or losing of electrons in order to fill or empty the outermost shell. Therefore, having eight electrons in the outermost shell is optimal for stability.

    A ________ ________ is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms.

    Explanation
    A covalent bond is a type of chemical bonding where atoms share pairs of electrons. In this type of bond, electrons are not transferred from one atom to another, but instead, they are shared between the atoms involved. This sharing of electrons allows both atoms to achieve a stable electron configuration, resulting in a strong bond between them. Covalent bonds are typically formed between nonmetal atoms and are responsible for the formation of molecules.

    The ________ ________ is a simple chemical rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells.

    Explanation
    The Octet Rule is a chemical principle stating that atoms tend to combine in a way that allows them to have eight electrons in their outermost energy level, also known as the valence shell. This rule is based on the observation that atoms are more stable when their outermost energy level is filled with eight electrons, achieving a configuration similar to the noble gases. By following the Octet Rule, atoms can form chemical bonds to gain, lose, or share electrons with other atoms, resulting in the formation of stable compounds.

    A ________ bond is created when one electron pair is shared by two atoms in a covalent bond.

    Explanation
    A single bond is created when one electron pair is shared by two atoms in a covalent bond. In a covalent bond, atoms share electrons in order to achieve a stable electron configuration. In a single bond, one electron pair is shared between the two atoms, resulting in the formation of a strong bond. This type of bond is commonly found in molecules and compounds, and it is the simplest and most common type of covalent bond.

    _________ _________ diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.

    Explanation
    Lewis Dot diagrams are used to represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist in the molecule. These diagrams show the arrangement of atoms and the sharing or transfer of electrons between them. By using dots to represent valence electrons, Lewis Dot diagrams provide a visual representation of the electron distribution in a molecule, allowing us to understand the bonding and structure of the molecule.

    Covalency is greatest between atoms of similar ________.

    Explanation
    Covalency refers to the sharing of electrons between atoms in a covalent bond. When atoms have similar electronegativities, it means they have similar abilities to attract electrons. In such cases, the sharing of electrons is more equal, resulting in a stronger covalent bond. Therefore, covalency is greatest between atoms of similar electronegativities.

    In a covalent bond, the two atoms do not need to be the same but must have similar ________.

    Explanation
    In a covalent bond, the two atoms share electrons. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. When two atoms have similar electronegativities, they have similar abilities to attract electrons, resulting in a balanced sharing of electrons in the covalent bond. This balance allows the atoms to form a stable bond and share electrons in a mutually beneficial way.

    The bond formed when Mg combines with O2 is ________

    Explanation
    When magnesium (Mg) combines with oxygen (O2), an ionic bond is formed. Ionic bonds occur between atoms with a large difference in electronegativity, where one atom (in this case, oxygen) gains electrons and becomes negatively charged (anion), while the other atom (magnesium) loses electrons and becomes positively charged (cation). This electrostatic attraction between the oppositely charged ions results in the formation of an ionic bond.
