    The options

    Select one:

    a. a 3 - ion forms.

    b. the noble gas configuration of argon is achieved.

    c. the result is a configuration of 1s2 2s2 2p6.

    d. the atom gains five electrons.

    Answer:

    c. the result is a configuration of 1s2 2s2 2p6.

    Explanation:

    Aluminium atom has atomic number of 13, hence the number of electron is 13 for a neutral atom of aluminium. When aluminium atom reacts with other elements it usually gives out three electron to attain the octet configuration.

    The cation representation of aluminium is Al3 + because it has loss three electron to attain the octet rule. Aluminium will be left with 10 electrons after losing 3 of it electrons. The electronic configuration will be represented as follows after losing three electrons;

    1S² 2S² 2P∧6.

    At this stage the octet rule has been achieved as it will be represented as

    2 8. The first energy shell now contains two electron and the second energy shell contains 8 electrons.

    The configuration of Neon has been formed in the process.
