Naming Ionic Compounds

posted by .

Can you please have a look at my questions. Thank you very much in return:-)

1. Will 2 metals develop an ionic compound? Clarify.

I don't think they will, but I don't know how to explain. I only know that in order to form ionic compounds, the total number of electrons given up by the metal ions must exatcly balance the toal number of electrons gained by the non-metal ions. - please help

2.write the name and symbol for the ion of each element listed below.

a-sodium= sodium, NA
b-chlorine= Chloride, Cl
c-copper with an ion charge of 2+= Copper(II), Cu

d-aluminum= aluminum, Al
e-phosphorus= phosphoride, P

3.write the name of the ion for each of the following non-metal elements. Am I just supposed to add ide at the end of them? I'm just a beginner on this, so I'm not sure If I've done all these correctly.

a-chlorine = chloride
b-bromine = Bromide
c-iodine = iodide
d-phosphorus = phosphide
e-oxygen = oxide
f-sulfur = sulfide
g-nitrogen = nitride?

4.write the name for each polyatomic ion.

a-SO4^2-^ =Sulphate
b-PO4^3+^ =Phospate
c-NO3 =Nitrate
d-OH- =Hydroxide
e-HCO3- =Hydrogen carbonate
f-Co3^2-^ =Carbonate

5. write the names of the compounds formed by the following combinations of elements.

a- sodium and iodine = sodium iodide
b- lithium and bromine = lithium bromide

c- silver and phosphorus = silver phosphate? phosphoride?

d- barium and oxygen = barium oxide

6.name the following ionic compounds

a-NaBr = Sodium Bromide
b-CaSo4 = Calcium Sulfate
c-K2S = Potassium Sulphide
d-Ni(NO3)2 = Nickel Nitrate
e-Mg3N2 = Magnesium Nitrate
f-Fe2(CO3)3 = Irom Carbonate
g-Cr2O3 = Chromium Oxide
h-Al2(SO2)3 = Aluminum Sulphite
i-Cu2SO4 = Copper Sulphate
j-Pb(NO3)4 = Lead Nitrate
I wasn't so sure about these.

7.Which of the following chemical formulas are correct? explain why the incorrect formulas are incorrect.

a-Al2O3 = incorrect
b-CrSO4 = incorrect
c-Fe3O2 = incorrect
d-Fe2(SO4)2 = ?

I don't really get this. Please help me explain:-(

    Both metals you are trying to combine have the same tendency to LOSE electrons (when combining with a non-metal, the metal is trying to lose, the non-metal is trying to gain and that makes a good fit. Two metals are trying to do the same thing; not a good fit.)

    2.write the name and symbol for the ion of each element listed below.
    I don't see a charge on ANY of your answers. The question wants the ion of the element listed.
    a-sodium= sodium, NA Na^+
    b-chlorine= Chloride, Cl Cl^-
    c-copper with an ion charge of 2+= Copper(II), Cu Cu^+2 or Cu(II)

    d-aluminum= aluminum, Al Al^+3
    e-phosphorus= phosphoride, P P and it may have +5, +3, or -3 charge

    3.write the name of the ion for each of the following non-metal elements. Am I just supposed to add ide at the end of them? I'm just a beginner on this, so I'm not sure If I've done all these correctly.

    a-chlorine = chloride
    b-bromine = Bromide
    c-iodine = iodide
    d-phosphorus = phosphide
    e-oxygen = oxide
    f-sulfur = sulfide
    g-nitrogen = nitride? You got them ALL. Very good!

    4.write the name for each polyatomic ion.

    a-SO4^2-^ =Sulphate
    b-PO4^3+^ =Phospate phosphate but it's a -3 charge, not +3)
    c-NO3 =Nitrate
    d-OH- =Hydroxide
    e-HCO3- =Hydrogen carbonate
    f-Co3^2-^ =Carbonate

    5. write the names of the compounds formed by the following combinations of elements.

    a- sodium and iodine = sodium iodide
    b- lithium and bromine = lithium bromide

    c- silver and phosphorus = silver phosphate? phosphoride? silver phosphate is correct

    d- barium and oxygen = barium oxide

    6.name the following ionic compounds

    a-NaBr = Sodium Bromide
    b-CaSo4 = Calcium Sulfate interesting that you named it sulphate above but sulfate here.
    c-K2S = Potassium Sulphide
    d-Ni(NO3)2 = Nickel Nitrate This is called, more properly, nickel(II) nitrate because Ni has oxidation states (common ones, anyway) of +2 and +3.
    e-Mg3N2 = Magnesium Nitrate Remember binary compounds always end in -ide. magnesium nitride
    f-Fe2(CO3)3 = Irom Carbonate iron(III) carbonate
    g-Cr2O3 = Chromium Oxide chromium (III) oxide
    h-Al2(SO2)3 = Aluminum Sulphite looks like a typo to me
    i-Cu2SO4 = Copper Sulphate another typo unless you meant copper(I) sulfate/sulphate.
    j-Pb(NO3)4 = Lead Nitrate lead(IV) nitrate
    I wasn't so sure about these.

    7.Which of the following chemical formulas are correct? explain why the incorrect formulas are incorrect.

    a-Al2O3 = incorrect looks ok to me.
    b-CrSO4 = incorrect looks ok to me
    c-Fe3O2 = incorrect I would buy into Fe2O3
    d-Fe2(SO4)2 = ? probably Fe2(SO4)3 but it might be FeSO4

    I don't really get this. Please help me explain:-(
