    (a) group and period in the Modern Periodic Table.

    (b) name and write its one physical property. [2]

    Answer:

    (a) Modern periodic law states that the physical and chemical properties of an element are the periodic function of the atomic number of that element.

    Electronic configuration of the elements play an important role in the placement of elements in the modem periodic table. The valence shell electron of an element decides its position in a particular group or period for example: if the configuration of an element is 2, 1 it means that the

    Li = 2, 1

    It belongs to the 2nd period and 1st group.

    Define the term power of accommodation. Write the modification in the curvature of the eye lens which enables us to see the nearby objects clearly? [2]

    Answer:

    The ability of the eye lens to adjust its focal length is called the power of accommodation. There should be a contraction . of ciliary muscles, that will increase the curvature of the eye lens and becomes thicker, so the focal length of the eye lens will decrease. It will thus enable us to see the objects clearly.

    Section – C

    (b) Potassium iodide reacts with lead nitrate to produce potassium nitrate and lead iodide. [3]

    Answer:

    Initially, the colour of silver chloride is white but when it is kept in sunlight it breaks down to give silver and chlorine. Hence, the colour changes to grey.

    It is an example of Photo-Chemical Decomposition.

    OR

    (a) The given reaction is a displacement reaction.

    (b) It is a double displacement reaction.

    Question 7.
