Which of the following elements has the electronic configuration [Ne]3s²3p⁵?

Which of the following elements has the electronic configuration [Ne]3s²3p⁵?

Step 1: Understand that the electronic configuration [Ne]3s²3p⁵ means that the element has the same electron configuration as Neon (Ne) plus additional electrons.
Step 2: Recognize that [Ne] represents the first 10 electrons, which is the configuration for Neon.
Step 3: Count the additional electrons: 3s² has 2 electrons and 3p⁵ has 5 electrons, totaling 2 + 5 = 7 additional electrons.
Step 4: Add the 7 additional electrons to the 10 from Neon, giving a total of 10 + 7 = 17 electrons.
Step 5: Identify the element with 17 electrons on the periodic table, which is Bromine (Br).
