The noble gas configuration for Br<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The noble gas configuration for bromine (Br) is:<\/p>\n\n\n\n

[Ar] 3d\u00b9\u2070 4s\u00b2 4p\u2075<\/strong><\/p>\n\n\n\n

Explanation<\/h3>\n\n\n\n

To determine the noble gas configuration for bromine, it helps to understand its position on the periodic table and the concept of noble gas shorthand notation. Bromine, with the atomic number 35, has 35 electrons. In shorthand notation, we express electron configurations by using the closest preceding noble gas configuration as a starting point, followed by the remaining electron configuration specific to the element.<\/p>\n\n\n\n

    \n
  1. Identify the Previous Noble Gas<\/strong>: For bromine, the noble gas that comes before it is argon (Ar), with an atomic number of 18. Therefore, argon\u2019s electron configuration, which is 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076<\/strong>, can be used as the base. This is written as [Ar]<\/strong>.<\/li>\n\n\n\n
  2. Determine Additional Electrons<\/strong>: After argon, we still need to account for 17 more electrons to reach bromine\u2019s total of 35. We add these electrons in the following order:<\/li>\n<\/ol>\n\n\n\n
      \n
    • 3d subshell<\/strong>: 10 electrons fill the 3d orbital completely, giving 3d\u00b9\u2070<\/strong>.<\/li>\n\n\n\n
    • 4s subshell<\/strong>: The next two electrons go into the 4s orbital, giving 4s\u00b2<\/strong>.<\/li>\n\n\n\n
    • 4p subshell<\/strong>: The remaining five electrons occupy the 4p orbital, giving 4p\u2075<\/strong>.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Resulting Configuration<\/strong>: When we combine all parts, the noble gas configuration for bromine becomes [Ar] 3d\u00b9\u2070 4s\u00b2 4p\u2075<\/strong>.<\/li>\n<\/ol>\n\n\n\n

        Why Noble Gas Configurations Are Useful<\/h3>\n\n\n\n

        Noble gas configurations are a streamlined way of expressing electron arrangements. They simplify complex configurations by focusing only on valence electrons, which play a primary role in chemical behavior. For bromine, the configuration 4s\u00b2 4p\u2075<\/strong> shows that bromine has seven valence electrons (in the fourth energy level), similar to other halogens, which need only one more electron to reach a stable, filled shell. This explains bromine\u2019s reactivity and tendency to form bonds by accepting an electron, particularly in ionic compounds or covalent bonding situations.<\/p>\n","protected":false},"excerpt":{"rendered":"
