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?

Respuesta :

adioabiola

The electronic configuration for magnesium in the shell of the atom is 2,8,2

This means that shell K will take 2electrons, L will take 8electrons and M will take 2 electrons

What is an element?

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, the electronic configuration for magnesium in the shell of the atom is 2,8,2
