Question

16. Explain in words the meaning of the "octet rule". 17. Write an equation for the reaction of Calcium metal with molecular oxygen to form calcium oxide. For each reactant and product atom or ion, write the electron configuration. Write the Lewis dot symbol for each reactant and product in the reaction. 18. Draw the Lewis dot structure for Carbon Dioxide, CO2, and identify all bonding and non-bonding electron pairs. 19. Draw the Lewis dot structure for propane, CaHs, showing all bonding and non-bonding electron pairs.

Explanation / Answer

16) An octet rule is one, that having eight electron in their outermost orbital. By attaining octet configuration an atom gets stability and it is the reason for which atoms form bond. Octet configuration, more specifically the configuration of the inert gases i.e.- ns2np6. It is the octet configuration which makes the elements of group zero (Ne to Rn ) inert. (Helium is an exception which contains two electron but still it act as an inert gas)
