The ground state electronic configuration of Fe atom is [Ar] 3d6 4s2. Electronic configuration of Fe2+ ion: [Ar] 3d6.
Which element has the electron configuration Ar 3d7 4s2?
The electron configuration for cobalt is [Ar] 3d7, 4s2.
What cation has the ground state electron configuration Ar 3d6?
Co3+
Correct option d Co3+Explanation :The electronic configuration of the given ions is :Thus Co3+ is the ion with the desired configuration.
What is the atomic number of elements whose outermost electron is represented by 3d6?

How do you write the electron configuration of an element?
1) Choose an element and write its electronic configuration. 2) Using Octet Rule, arrange the electrons to its orbital shells based on electron configuration. 3) Trace out the number of electrons present in the outer most shell. 4) Make use of periodic table rows and determine orbital shells.
How many electrons are in a 3D electron configuration?
And for the next nine elements (ending with zinc), the 3d is gradually filled up to 10 electrons, with iron the 6t
Why does Fe2+ have a 3d6 electron configuration?
Hund’s rule states that electrons fill in the suborbitals singly before pairing. Fe2+ means Iron has lost two electrons, thus we have 3d6 configuration instead of the above mentioned in the outermost subshell.. D-orbital can take 10 electrons but we have 6 electrons.
What is the electron configuration of BA in electron configuration?
