Question

explain the valency of iron (in simple words)

Answer 1

Iron (Fe) has an atomic number of 26, i.e. has 26 electrons. When iron loses the 2 4s electrons, it attains a valency of +2. Sometimes, iron will also lose one of the paired electrons from 3d orbital, leaving the entire 3d orbital filled with unpaired electrons (which provides a more stable configuration).

Answer 2

Answer:

Iron (Fe) has an atomic number of 26, i.e. has 26 electrons. ... When iron loses the 2 4s electrons, it attains a valency of +2. Sometimes, iron will also lose one of the paired electrons from 3d orbital, leaving the entire 3d orbital filled with unpaired electrons (which provides a more stable configuration).

Here is your answer
