Identify the total number of electrons in the Bohr model by adding the electrons in each shell: 2 electrons in the first shell plus 6 electrons in the second shell, giving a total of 8 electrons.
Recall that the number of electrons in a neutral atom equals the atomic number, which determines the element's identity on the periodic table.
Look up the element with atomic number 8, which corresponds to the total number of electrons counted.
Recognize that the element with atomic number 8 is oxygen.
Confirm that the electron configuration (2 electrons in the first shell and 6 in the second) matches the known electron arrangement for oxygen.
