Problem: A main group metal was studied and found to exhibit the following properties:It does not occur free in nature.It loses valence electrons readilyIt reacts readily with the halogens, oxygen, and nitrogen.It is produced by high-temperature reduction of its oxide.It reacts vigorously with water.Which of the following metals might have been the element studied?A) LiB) SrC) BaD) AlE) NaThe main group elements of the periodic table are those found in groups 1A through 8A. The members of a group exhibit similar properties owing to the similarity in their outer electron configurations. Although the properties are similar, they are not identical, and they vary from top to bottom of a column. As a result, each element has a unique set of properties that can be used to identify it.

The main group elements of the periodic table are those found in groups 1A through 8A. The members of a group exhibit similar properties owing to the similarity in their outer electron configurations. Although the properties are similar, they are not identical, and they vary from top to bottom of a column. As a result, each element has a unique set of properties that can be used to identify it.
