Question

Draw the atom of Magnesium (#12 on Periodic Table) to answer: which of the following is TRUE about its structure:

a.) The valency of magnesium will be 2
b.) Magnesium becomes a cation
c.) In neutral form, electrons of magnesium occupy 3 orbits
d.) All of the above are true

Answer 1

The statements regarding magnesium's atomic structure being that it has a valency of 2, forms a cation with a 2+ charge, and its electrons occupy three orbits in its neutral state are all correct. Therefore, 'all of the above' is the true answer regarding magnesium's structure.

Step-by-step explanation:

Magnesium Atom Structure and Properties

Magnesium, with the atomic number 12, has several key properties:

The valency of magnesium is indeed 2, because to reach the stable electron configuration of the nearest noble gas, neon, magnesium must lose two electrons.

When magnesium becomes a cation, it loses two electrons and forms a Mg2+ ion, which illustrates its cationic nature.

In its neutral form, magnesium's electrons will occupy three orbits; two in the 1s orbit, eight in the 2s and 2p orbits combined (which complete the neon configuration), and the remaining two in the 3s orbit as its valence electrons.

Considering all the given points, we can determine that all of the above statements are indeed true.
