Q&A ON THE GROUP

• Does the group have a name that it is usually referred to? | Yes. The nitrogen family.
• What does it consist of? | Consists of two metalloids, one metal, and one with unknown properties.
• How are the elements similar? | All elements involved are solids at room temp, except for nitrogen which is a gas at room temp.
• What is something interesting about one element? | phosphorus can be found in our bones and teeth and is a necessary part of our diet.
• Are plants ever involved with the elements? | one example of a plants reaction is phosphorus making algae grow excessively.
