A model of an atom with eight electrons corresponds to the element oxygen, which has atomic number 8. In a simplified atomic model, such as the Bohr model, these electrons would be arranged in energy levels or shells around the nucleus.
In oxygen:
- The nucleus contains 8 protons and usually 8 neutrons (making the most common isotope of oxygen, oxygen-16).
- The first energy level can hold a maximum of 2 electrons, which is filled by the first two electrons.
- The second energy level can hold up to 8 electrons. In the case of oxygen, this level has 6 electrons, as oxygen has a total of 8.
This arrangement leads to oxygen having a valence of 2 (due to the 6 valence electrons in the outer shell), which makes it reactive and capable of forming bonds with other elements, such as hydrogen, to form water (H2O). This also ties into the octet rule, stating that atoms tend to bond in such a way that they achieve a full outer shell, usually consisting of 8 electrons.
