Two representative elements , nitrogen and ogen, are in the same period of the periodic table. Which statement correctly describes the atoms of the 2 elements

Answer 1

It seems there was a typographical error in your question, likely referring to "oxygen" instead of "ogen." Both nitrogen (N) and oxygen (O) are indeed representative elements, but they are not in the same period of the periodic table. Nitrogen is in period 2, while oxygen is also in period 2.

Here’s a correct statement to describe these two elements:

1. Both nitrogen and oxygen are nonmetals that belong to Group 15 (nitrogen) and Group 16 (oxygen) of the periodic table, respectively.
2. Both elements have similar physical properties such as being gases at room temperature.
3. Nitrogen exists primarily as a diatomic molecule (N₂), while oxygen exists primarily as O₂.
4. Nitrogen has five valence electrons, while oxygen has six valence electrons, which influences their chemical behavior and reactivity.

If you meant to ask something more specific or different, please clarify!
