Oxygen is a common element that exists in two forms, oxygen gas and ozone gas. Write the electron configurations for the oxygen atom and the oxygen ion using spdf notation.

there all right good

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
