Question

Which one of the following statements is true for an atom that has full s and p orbitals in its outermost energy level?

A. It's highly reactive only with halogens.
B. It has a stable octet and is unreactive.
C. It's highly reactive only with alkali metals.
D. It can be combined with most elements.

2 Answer

  • Answer:

    B. It has a stable octet and is unreactive.

    Explanation:

    s orbital contains 2 electrons and p contains 6. When the outermost energy level of an element has a total of 8 electrons we call it stable octet and it is unreactive. Therefore the answer is B

  • Answer:

    B.

    Explanation:

    For example the element with configuration

    1s2 2s2 2p6 which is Neon, an inert.

    It has a stable 8 electrons in its outermost shell which makes it stable.
