The properties of nitrogen would be more similar to the properties of phosphorous. 
Step-by-step explanation: 
Both nitrogen and phosphorous belong to group 15(VA) elements as represented in the periodic table of elements. 
They are present with similar electronic configuration with five valence electrons(s subshell-2, p shell-3 unpaired), form covalent compounds, shares oxidation numbers of +3 and +5. Hence, the chemical behavior or properties of both nitrogen and phosphorus are similar.
 The nitrogen family members are collectively called as pnictogens or pentels and include – nitrogen, phosphorus, bismuth, arsenic, and antimony. 
Neon is a group 18 element of the noble gas family and hence its properties would differ with nitrogen.
