Question

Write configuration of Fe³+ ion atomic No.-26​

Answer 1

Explanation:

The electron configuration for the Fe3+ ion is 1s2 2s2 2p6 3s2 3p6 3d5. Normally, a neutral atom of iron would have two electrons in the 4s sublevel and six electrons in the 3d sublevel

Answer 2

Answer:

1s22s22p63s23p63d64s2

For the Fe2+ ion we remove two electrons from 4s2 leaving us with: 1s22s22p63s23p63d6

For the Fe3+ ion we remove a total of three electrons (two from the 4s2 and one form the 3d6) leaving us with 1s22s22p63s23p63d5 1s2 2s2 2p6 3s2 3p6 3d5

The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds
