If you look at the periodical table:

Phosphorus (15); Arsenic (33); Antimony (51); Bismuth (83) and Ununpentium (115) are directly on top of each other. this means their properties are similar because they all have 3 electron in its outer shell.

Phosphorous (atomic # 15) because it is right below it in the periodic table. Things in the same columns have similar chemical properties.
