      2 electrons

    Correct Answer
    B. 4 valence electrons
    Explanation
    Carbon is able to bond with atoms of other elements in many different ways because it has 4 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, and they determine how an atom will bond with other atoms. Carbon has 4 valence electrons, which allows it to form stable covalent bonds with other atoms by sharing electrons. This ability to form multiple bonds and create a variety of compounds is what makes carbon the basis of organic chemistry.

    Correct Answer
    B. Valence electrons
    Explanation
    Each family in the periodic table has its own characteristic properties based on the number of valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and they determine the chemical behavior of the element. The number of valence electrons determines the element's reactivity and its ability to form chemical bonds with other elements. Therefore, the number of valence electrons is crucial in understanding the properties and behavior of each family in the periodic table.

    • A.

      Positive ion

    • B.

      Negative ion

    Correct Answer
    A. Positive ion
    Explanation
    When an atom loses an electron, it becomes a positive ion. This is because the atom now has more protons than electrons, resulting in a net positive charge. The loss of an electron creates an imbalance in the atom's charge, causing it to become positively charged. Positive ions are attracted to negative ions or other atoms with a higher electron density, and they play important roles in chemical reactions and electrical conductivity.

      Fun and boring ions

    Correct Answer
    A. Negative and positive ions
    Explanation
    An ionic bond is the attraction between negative and positive ions. In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively charged ions and negatively charged ions. These opposite charges then attract each other, creating a strong bond between the two ions. This bond is formed through electrostatic forces and is typically found in compounds where one element is a metal and the other is a non-metal.
