Question

The electron configuration for magnesium is shown below. 1s22s22p63s2 Which diagram shows the correct distribution of electrons in the electron shells of a magnesium atom?

Answer 1

The diagram showing configuration of magnesium is :-

Answer 2

Answer: The diagram showing distribution of electrons is shown in the image attached.

Explanation: The distribution of electrons are done in the shells of an element.

Magnesium is the 12th-element of the periodic table having 12 electrons which are distributed in the shells of n = 1, 2 and 3.

The electronic configuration of Magnesium element is : $1s^2s^22p^63s^2$

The image showing distribution of electrons in Magnesium atom is shown in the image below.
