The Nitrogen Group
This group includes different types of natural element – non-metals,
semi-metals, and dense metals – as well as moscovium (Mc), an artificial
element. The group is also known as “pnictogens”. This derives from
the Greek word pnígein, which means “to choke” and refers to the
potential toxicity of nitrogen (N) in certain forms.
