Question

i am a group 15 element. i am a gas at room temperature. and i am most commonly found as a diatomic molecule. who am i? view periodic table tap on an option below to select or deselect an answer. astatine (at) arsenic (as) antimony (sb) arsenic (as) bromine (br) bismuth (bi) chlorine (cl) phosphorus (p) oxygen (o) nitrogen (n)

Explanation:

1. First, identify Group 15 elements from the options: Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), Bismuth (Bi).
2. Next, filter for elements that are gases at room temperature: only Nitrogen (N) fits this criterion among Group 15 elements.
3. Confirm Nitrogen is commonly found as the diatomic molecule $\text{N}_2$, which matches all given clues.

Answer:

Nitrogen (N)
