  1. Asked: April 29, 2024In: Class 9 Science

    What is valency, and why is it significant in chemistry?

    Rajbir Singh
    Added an answer on April 30, 2024 at 8:59 am

    Valency is the measure of an element's ability to form chemical bonds, indicating the number of electrons an atom can gain, lose, or share to achieve a stable electron configuration. It's crucial in determining an element's reactivity and the types of compounds it can form.

  2. Asked: April 29, 2024In: Class 9 Science

    What is the valency of oxygen obtained through this calculation?

    Rajbir Singh
    Added an answer on April 30, 2024 at 8:59 am

    The valency of oxygen is 2. It is obtained by subtracting the number of valence electrons (6) from the octet rule (8), representing its tendency to gain 2 electrons in bonding.

  3. Asked: April 29, 2024In: Class 9 Science

    How does this method apply to determining the valency of oxygen?

    Rajbir Singh
    Added an answer on April 30, 2024 at 8:59 am

    This method applies by considering oxygen's position in the periodic table, with 6 valence electrons. Subtracting this from the octet rule (8) yields its valency of 2.

  4. Asked: April 29, 2024In: Class 9 Science

    Why is it easier for fluorine to gain electrons rather than lose them to achieve a full outer shell?

    Rajbir Singh
    Added an answer on April 30, 2024 at 8:59 am

    Fluorine has 7 valence electrons and needs only one more to achieve a full outer shell, making it easier to gain an electron rather than lose seven. This electron gain fills its outer shell, stabilizing its electron configuration.

  5. Asked: April 29, 2024In: Class 9 Science

    What is the valency of fluorine according to this method?

    Rajbir Singh
    Added an answer on April 30, 2024 at 8:59 am

    The valency of fluorine is 1. By considering its position in the periodic table with 7 valence electrons, it needs to gain only 1 electron to achieve a full outer shell configuration.
