Transcript text: What is the symbol for the ion formed by magnesium?
Multiple Choice
$\mathrm{Mg}^{2-}$
$\mathrm{Mg}^{3+}$
$\mathrm{Mg}^{2+}$
$\mathrm{Mg}^{4}$
$\mathrm{Mg}^{3-}$
Solution
Solution Steps
Step 1: Understanding Magnesium's Position in the Periodic Table
Magnesium is an element located in Group 2 of the periodic table. Elements in this group are known as alkaline earth metals and typically form ions with a +2 charge.
Step 2: Determining the Ion Charge
Magnesium has two electrons in its outermost shell. To achieve a stable electron configuration similar to the nearest noble gas (neon), magnesium tends to lose these two electrons. This results in a cation with a charge of +2.
Step 3: Identifying the Correct Ion Symbol
Given that magnesium loses two electrons to form a stable ion, the correct symbol for the ion formed by magnesium is \(\mathrm{Mg}^{2+}\).
