Question

A scientist performs an experiment on an unknown element. She finds that the element forms and ionic bond with beryllium but not lithium. She concludes that the unknown element must belong in group 2 of the periodic table. State whether or not you think this result supports her conclusion, and why.

2 Answer

  • Answer: This results does not support her conclusion.

    Explanation:

    When a scientist performs an experiment and fins out that an element forms an ionic bond with beryllium but not with lithium.

    Beryllium is an element of group 2 and it forms an ionic bond with non-metals.

    Non-metals are the elements that belong from Group 15 to Group 17.

    Therefore, the unknown element must belong to the groups from Group 15 to Group 17.

    Hence, her conclusion the the unknown element belong to group 2 is wrong.

  • The result of the test which shows a bond with beryllium but not lithium does not support her conclusion.

    Why is her conclusion wrong?

    • Group 2 elements would not form an ionic bond with another group 2 element.
    • They would need to bond with a nonmetal that requires electrons to be stable.

    The element bonded with Beryllium which is in group 2 so could not be in group 2 as well. The unknown element was most likely a nonmetal.
