Group 15 is the 15th column in the periodic table of elements. It includes nitrogen, phosphorus, arsenic, antinomy, bismuth, and ununpentium. Group 15 elements are called pnictogens & pnicogens.
nitrogen phosphorus potassium
Phosphorus is in the 15th column of the periodic table (Nitrogen group) That means that it has similar valence shell electronic properties as nitrogen arsenic antimony bismuth
A family is another name for a group. Groups are the vertical columns on the table. Phosphorus is in group 15, or 5A
These are the pnictogens and you can remember them by the first two letters of two pnictogens. P, phosphorus; N, nitrogen.
