The elements in a same group tends to form ions with the same charge. It is most consistent at each end of the periodic table.
The ionic compound containing the polyatomic ion NaNO₃ is sodium nitrate. It consists of sodium ions (Na⁺) and nitrate ions (NO₃⁻). In this compound, each sodium ion pairs with one nitrate ion, resulting in a neutral compound that is commonly used as a fertilizer and in food preservation.
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
CoBr2 is composed of cobalt ions (Co²⁺) and bromide ions (Br⁻). In this compound, each cobalt ion has a +2 charge, while each bromide ion has a -1 charge. As there are two bromide ions for each cobalt ion, the overall charge balance is maintained, resulting in a neutral compound. Thus, the formula reflects one cobalt ion and two bromide ions.
The compound NH4₂Cr₂O7, known as ammonium dichromate, contains two ions: the ammonium ion (NH4⁺) and the dichromate ion (Cr2O7²⁻). Each formula unit of ammonium dichromate consists of two ammonium ions and one dichromate ion, balancing the overall charge of the compound. The ammonium ion carries a +1 charge, while the dichromate ion carries a -2 charge.
The answer is Hydrate.
The ionic compound containing the polyatomic ion NaNO₃ is sodium nitrate. It consists of sodium ions (Na⁺) and nitrate ions (NO₃⁻). In this compound, each sodium ion pairs with one nitrate ion, resulting in a neutral compound that is commonly used as a fertilizer and in food preservation.
Polyatomic ions are named with their specific names, regardless of their overall charge. When naming an ionic compound with a polyatomic ion, the name of the cation is written first followed by the name of the anion (polyatomic ion).
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
The compound PbCl4 is made up of lead (Pb) ions and chloride (Cl-) ions. In this compound, the lead atom has a charge of +4, and each chloride ion has a charge of -1, so it forms four chloride ions to balance the charge of the lead ion.
CoBr2 is composed of cobalt ions (Co²⁺) and bromide ions (Br⁻). In this compound, each cobalt ion has a +2 charge, while each bromide ion has a -1 charge. As there are two bromide ions for each cobalt ion, the overall charge balance is maintained, resulting in a neutral compound. Thus, the formula reflects one cobalt ion and two bromide ions.
ferrous ions and Fe3+ is ferric ion
Na+ and C2H3O2- are the two ions in the compound sodium acetate.
If the compound contains a polyatomic ion, simply name the ion.
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
Potassium Phosphate K3PO4 3 K ions and 1 PO4 ion
The Arrhenius acids give proton or hydrogen ion or hydronium ion in water.
The formula for the ionic compound formed by the calcium ion (Ca^2+) and the phosphate ion (PO4^3-) is Ca3(PO4)2, known as calcium phosphate. In this compound, three calcium ions combine with two phosphate ions to balance the charges and form a neutral compound.
