Answer to Question #86289 in Inorganic Chemistry for Tanko Miyabe

Question

One of these elements behave partly as the alkaline metals as well as a hologen element

Answer 1

Solution.

The element exhibiting the properties of alkali metals and halogens is hydrogen. In its electronic structure, one electron is missing for filling the energy level, as in halogens. However, it has only one electron on the outer layer, which relates it to the group of alkali metals. In addition, hydrogen is a reducing agent, as alkali metals, and not as halogens, which at the beginning of their seventh group are strong oxidizing agents.

Answer:

Hydrogen (H2)
