Studdy Solution

STEP 1

Assumptions1. The compound is Mg3 \mathrm{Mg}_{3} \mathrm{~}_{}. . The compound is neutral, meaning the total positive charge equals the total negative charge.
3. The charge on an ion is determined by its position in the periodic table.

STEP 2

First, we need to determine the charge on the magnesium ion. Magnesium is in the second group of the periodic table, so it tends to lose two electrons to achieve a stable electron configuration. This gives it a charge of +2.
Mg charge+2Mg\, charge +2

STEP 3

Next, we need to determine the charge on the nitrogen ion. Nitrogen is in the fifth group of the periodic table, so it tends to gain three electrons to achieve a stable electron configuration. This gives it a charge of -3.
 charge−3\, charge -3

STEP 4

Now, we need to verify that the total positive charge equals the total negative charge in the compound. There are three magnesium ions and two nitrogen ions in the compound.
Total positive charge=3×Mg charge=3×+2=+6Total\, positive\, charge =3 \times Mg\, charge =3 \times +2 = +6Total negative charge=2×N charge=2×−3=−6Total\, negative\, charge =2 \times N\, charge =2 \times -3 = -6The total positive charge equals the total negative charge, so the compound is neutral.

STEP 5

Finally, we need to name the compound. The cation (positive ion) is named first, followed by the anion (negative ion). The name of the cation is the same as the name of the element. The name of the anion is the root of the element name plus the suffix "-ide".NameMagnesium NitrideName Magnesium\, NitrideMg charge +2$$ charge -3Name Magnesium Nitride
