According to the Oddo-Harkins rules elements having even atomic numbers are more common than those elements who have odd atomic numbers but there is an exception for hydrogen. The rule argues that one unpaired proton in the odd atomic numbers is more likely to capture another one and hence the atomic number is increased. The … Read more
