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)\no they have the same number of electrons.\no they have valence electrons in the same energy level.\no they have valence electrons in different energy levels.\no they have the same number of valence electrons.

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)\no they have the same number of electrons.\no they have valence electrons in the same energy level.\no they have valence electrons in different energy levels.\no they 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 principal energy level. Nitrogen and oxygen are in period 2. Nitrogen has 7 electrons and 5 valence electrons, oxygen has 8 electrons and 6 valence electrons. So they don't have the same number of electrons or valence electrons, but their valence electrons are in the second energy level.

Answer:

They have valence electrons in the same energy level.
