Questions & Step-by-Step Solutions

Which of the following has the electronic configuration [Kr] 5s2 4d10 5p5?
Correct Answer: Astatine
  • Step 1: Understand that the electronic configuration is a way to describe the arrangement of electrons in an atom.
  • Step 2: Recognize that [Kr] represents the electron configuration of Krypton, which has 36 electrons.
  • Step 3: The notation 5s2 means there are 2 electrons in the 5s subshell.
  • Step 4: The notation 4d10 means there are 10 electrons in the 4d subshell.
  • Step 5: The notation 5p5 means there are 5 electrons in the 5p subshell.
  • Step 6: Add the total number of electrons: 36 (from Kr) + 2 (from 5s2) + 10 (from 4d10) + 5 (from 5p5) = 53.
  • Step 7: Identify the element with atomic number 53, which is Astatine.
