Bohr's Model of the Atom
An element in the alkaline earth metals family has three rings in its Bohr diagram. What is this element?​

Answer:

Magnesium ([tex]{\rm Mg}[/tex].)

Explanation:

In the Bohr Model of atoms, each "ring" denotes a non-empty main energy shell. The Bohr Model for this atom has three rings, meaning that three of the main energy shells of this atom contain electron(s).

Refer to a copy of the modern periodic table. Elements on the modern periodic table are arranged into rows ("periods") by the number of non-empty main energy shells in each atom.

There are three non-empty main energy shells in the atom in this question. Thus, the element of this atom would belong to the third period (third row) of the modern periodic table.

Examples of alkaline-earth metal elements include Beryllium, Magnesium, Calciums, and a few others. These elements are in IUPAC group [tex]2[/tex] and are found in the second column from the left of a modern periodic table.

There is only one alkaline-earth metal in each period. The question implied that the element here includes three non-empty main energy shells per atom. That element would thus be in the third period. The alkaline-earth metal of the third period is magnesium. Therefore, the element in this question would be magnesium.
