two representative elements, nitrogen and oxygen, are in the same period of the periodic table. which statement correctly describes the atoms of the two elements? (1 point)\nthey have the same number of electrons.\nthey have valence electrons in the same energy level.\nthey have valence electrons in different energy levels.\nthey have the same number of valence electrons.

Answer

Brief Explanations:

Elements in the same period of the periodic table have their valence electrons in the same energy - level. Nitrogen has 7 electrons and oxygen has 8 electrons, so they don't have the same number of electrons. Nitrogen has 5 valence electrons and oxygen has 6 valence electrons, so they don't have the same number of valence electrons either.

Answer:

They have valence electrons in the same energy level.
