![]() ![]() The electronic configuration of oxygen can be represented as 1s^2 2s^2 2p^4, where the superscript numbers indicate the number of electrons in each subshell. Electrons are arranged in energy levels or shells around the nucleus, with the first shell holding a maximum of 2 electrons and the second shell holding a maximum of 8 electrons. In a neutral oxygen atom, the number of electrons is also 8, balancing out the positive charge of the protons. The atomic number of oxygen is 8, which means it has 8 protons in its nucleus. Description of the Atomic Number and Electronic Configuration of Oxygen In this section, we will explore the Lewis dot structure of oxygen and understand how it achieves stability through the formation of double covalent bonds. Oxygen is essential for life as it plays a crucial role in various biological and chemical processes. It is a highly reactive nonmetal and a member of the chalcogen group on the periodic table. Oxygen is a chemical element with the symbol O and atomic number 8.
