Question
The elements with atomic numbers 35 and 53 have similar chemical properties. Based on their electronic configurations, predict the atomic number of a heavier element that also should share these chemical properties.
Step 1
The element with atomic number 35 is bromine (Br), and its electronic configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^5. The element with atomic number 53 is iodine (I), and its electronic configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 Show more…
