Question

What is the atomic number of the element whose outermost electron is represented by 3d6?

Answer 1

Answer:26

Explanation:

Answer 2

Answer:

Atomic Number is 26.

Explanation:

Since we need to find the Element whose outermost electron is represented by $3d^{6}$.

We know the representation of electronic configuration.

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}...............$

We need to find till $3d^{6}$.

So,

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{6}$

So, it contains only 26 electrons in it.

We know that the atomic number is defined as the number of electrons.

So, atomic number of Element whose outermost electron is represented by $3d^{6}$ is 26.

Element whose Atomic number 26 is Iron.
