Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is the virus causing the COVID‐19 disease. Data regarding the morphological properties of this virus are collected from the literature and then the energy stored in each structural element is calculated with Domalski and Hearing's group contribution method. Viruses, including the Corona viruses, derive all of their energy from the host cell and carry out all of their activities with this energy. SARS‐CoV‐2 construct a vehicle needed for the delivery of its mRNA to other hosts to inflict them with the disease. Upon transfer of the viral RNA to the new host, the remaining parts of the viral structure are discarded. Structural and molecular assessments showed that the chemical formula of SARS‐CoV‐2 virus is C 7,336,852 H 12,384,463 N 1,247,424 O 1,915,357 P 100,231 S 25,084 and its enthalpy of formation is −8.70 × 10 −16 kJ. Comparison of SARS‐CoV‐2 with the other viruses shows that its elemental composition does not like any of the others. The results of this study are expected to improve our knowledge of the thermodynamic properties of this virus.
