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

Answer 1

The correct statement that describes the atoms of nitrogen and oxygen is:

They have valence electrons in the same energy level.

Both nitrogen and oxygen are in the second period of the periodic table and thus have their valence electrons in the same energy level (the second energy level). Nitrogen has 5 valence electrons, while oxygen has 6 valence electrons.
