Amain group metal was studied and found to exhibit the following properties: it does not occur free in nature. it loses valence electrons readily. it reacts readily with the halogens, oxygen, and nitrogen. it is produced by high-temperature reduction of its oxide. it reacts vigorously with water.

This group metal is Barium (Ba)

Explanation:

Metals generally loses valence electrons easily. Barium is a chemical-like, but more volatile, metallic component of calcium. It is a smooth, silvery metal, and due to the formation of barium oxide (BaO), this quickly turns a black color when sliced. It is also extremely liquid and alcohol reactive.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
