Mg  and  nitrate

BlackTom AI · Accepted Answer

The task asks for the ionic compound formed from magnesium (Mg) and nitrate (NO3−), along with its name.
First, identify the ions involved: magnesium typically forms a Mg2+ cation, since magnesium is in Group 2 and loses two electrons. The nitrate ion NO3− carries a −1 charge.
To achieve electrical neutrality, you need two nitrate anions to balance the 2+ charge of Mg2+. This leads to the formula Mg(NO3)2, where the magnesium cation is paired with two nitrate anions.
Parsing the formula: Mg at the center, with two NO3− groups attached, giving the overall neutral compound Mg(NO3)2.
For naming, follow the standard convention for ionic compounds: name the cation first (magnesium) followed by the name of the anion, which is nitrate. Since there are two nitrate groups, the name remains magnesium nitrate.
Note on provided options: there were no alternative answer choices given to compare against, so this reasoning focuses on the established charges and polyatomic ion composition to justify why Mg(NO3)2 is the correct formula and why its name is magnesium nitrate.
