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)

Question

Responses

They have the same number of electrons.
They have the same number of electrons.

They have valence electrons in the same energy level.
They have valence electrons in the same energy level.

They have valence electrons in different energy levels.
They have valence electrons in different energy levels.

They have the same number of valence electrons.

Answer 1

The correct statement is:

They have valence electrons in the same energy level.

Nitrogen and oxygen are both in the second period of the periodic table. They have their valence electrons in the same energy level (the second energy level), but they have different numbers of valence electrons: nitrogen has 5 and oxygen has 6. Therefore, the other options listed are not accurate.
