Ascientist performs an experiment on an unknown element. she finds that the element forms an ionic bond with beryllium (be) but not with lithium (li). 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

The result do not support her conclusion as group 2 elements are metals.

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element or non metal and forms a negatively charged ion called as anion.

As both Lithium (Li) and berrylium (Be) are metals, they would combine with a non metal to form ionic bond. Thus the unknown element must be a non metal and should belong to group 14 , 15 , 16 or 17 and not to group 2, which are metals.

Thus The result do not support her conclusion as group 2 elements are metals.
