    Hint: Compounds which are formed by complete transfer on one or more electrons from electropositive atom to electronegative element forms an ionic compound. Lewis symbols are used to express the valence electrons of atoms as a dot.Complete Step By Step Answer:

    As we know atomic number of calcium is

    (20) (20)

    , so its electronic configuration according to Aufbau’s principle will be

    1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 2 1s22s22p63s23p64s2

    . From the electronic configuration we clearly see that the calcium atom has two electrons in its outermost shell. So, if calcium loses its two electrons then it will attain the noble gas configuration.

    Similarly, atomic number of chlorine atom is

    (17) (17)

    , so its electronic configuration according to Aufbau’s principle will be

    1 s 2 2 s 2 2 p 6 3 s 2 3 p 5 1s22s22p63s23p5

    . From the electronic configuration we clearly see that the chlorine atom has seven electrons in its outermost shell. So, a chlorine atom requires one more electron to attain noble gas configuration.

    When a calcium atom reacts with two atoms of chlorine, each chlorine atom gains one electron from the calcium atom and forms the ionic compound.

    When calcium donates its electrons to chlorine atoms it become positive in nature while chlorine atom become negative in nature as

    [C a +2 ] [Ca+2] and [2C l − ] [2Cl−] .

    So, formation of calcium chloride with the help of electron dot structure is expressed as –:

    When we write the chemical formula of calcium chloride it will become

    CaC l 2 CaCl2 .

    Note:

    Calcium chloride is an example of ionic compound and shows good electrical conductivity only in aqueous state or in its molten state when it breaks down into its constituents’ ions. Dots shown in any Lewis structure are equivalent to valence electrons of atoms.

    Solution Verified by Toppr

    Correct option is C)

    An ionic bond is formed in a molecule when one atom in the molecule transfers one or more electrons from itself to its neighbouring atom in the molecule.

    In this molecule, calcium transfers its two electrons to its two neighbouring chlorine atoms and hence CaCl

    2 ​

    is an ionic compound.
