Question

nitrogen is a group 15 element. which statement about the other elements in group 15 is true? group 15 n nitrogen 15 p phosphorus 33 as arsenic 51 sb antimony 83 bi bismuth they look similar to nitrogen. they react in a way similar to how nitrogen reacts. they have the same density when under the same conditions. they are a gas at room temperature and standard pressure.

Explanation:

Elements in the same group of the periodic - table have similar chemical properties because they have the same number of valence electrons. Nitrogen and other Group 15 elements have 5 valence electrons, so they react in a way similar to how nitrogen reacts. Nitrogen is a gas at room temperature and standard pressure, while others like phosphorus, arsenic, antimony, and bismuth are solids. They do not look similar and do not have the same density under the same conditions.

Answer:

They react in a way similar to how nitrogen reacts.
