What are the charges of the ions in an ionic compound containing iron(III) and fluoride ions?
a)iron(III)- i got 3+
b) flouride- im not sure on this one
c)Write the formula for the compound. (Type your answer using the format CO2 for CO2.)
- Fe3F2... i rly have no idea on this one
nevermind i got it. thanks
iron(III) is +3
F is -1
FeF3 is iron(III) fluoride
How do you know the formula. If Fe is +3 and F is -1, it takes 3 F ions to make -3 and all compounds are zero. Fe is +3 and 3F are -3 and +3 + (-3) = 0 charge on the compound.
To determine the charges of the ions in an ionic compound containing iron(III) and fluoride ions, let's follow these steps:
a) The charge of iron(III) can be determined from its Roman numeral in parentheses. In this case, iron(III) means it has a +3 charge.
b) To find the charge of fluoride, we need to know that most nonmetals tend to gain electrons to achieve a full outer shell. Fluorine, which is a nonmetal, belongs to group 17 (or Group VIIA) of the periodic table, known as the halogens. Halogens have a charge of -1 when they form ions. Therefore, fluoride ions (F-) have a charge of -1.
c) To write the formula for the compound, we need to balance the charges between the iron(III) and fluoride ions. Since iron(III) has a +3 charge and fluoride has a -1 charge, we need three fluoride ions to balance the charge of one iron(III) ion. Therefore, the formula for the compound is FeF3.
So, the charges of the ions in the ionic compound containing iron(III) and fluoride ions are:
a) Iron(III): +3
b) Fluoride: -1
c) Formula: FeF3
To determine the charges of the ions in an ionic compound, such as iron(III) and fluoride ions, we need to use the principle of charge balance.
a) Iron(III) ions have a charge of 3+. This means that each iron atom loses three electrons to become a Fe3+ ion. The Roman numeral "III" indicates the charge of iron in this compound.
b) To determine the charge on fluoride ions, we need to use the charge balance principle. Since iron(III) ions have a charge of 3+, there must be three fluoride ions for every iron(III) ion to balance out the charges. This is because the total positive charge should be equal to the total negative charge in an ionic compound.
Therefore, fluoride ions (F-) have a charge of 1- because each fluoride ion gains one electron to become negatively charged.
c) To write the formula for the compound, we use the charges of the ions. Since the charge of iron(III) ion is 3+ and the charge of fluoride ion is 1-, we need to balance the charges. The ratio of ions in the compound is determined by the charges of the ions.
Since the charges need to balance out, we need three F- ions per one Fe3+ ion. Therefore, the formula for the compound is FeF3. The positive charge of Fe3+ balances with the three negative charges of three F- ions.
