Chlorine atoms have 7 valence electrons and need only 1 more in order to become stable (having 8 valence electrons). It takes much less energy to add an electron to a chlorine atom than it does to remove 7 valence electrons, so the chlorine atom gains one electron and becomes a negative ion with a 1- charge. The same thing is true of oxygen, except that it has 6 valence electrons, so it will gain 2 electrons and becomes a negative ion with a 2- charge.

Describe the structure of sodium chloride and magnesium oxide as solids?
Sodium chloride has a crystalline structure where each sodium ion is surrounded by six chloride ions and vice versa. Magnesium oxide has a three-dimensional lattice structure in which magnesium ions are surrounded by oxygen ions and vice versa.
What does zinc oxide with hydrochloric acid make?
When zinc oxide reacts with hydrochloric acid, it forms zinc chloride and water. This is a typical acid-base reaction in which the hydroxide ions from the zinc oxide react with the hydrogen ions from the hydrochloric acid to form water.
Which element reacts to form oxide ions?
Oxygen is the element that reacts to form oxide ions. Oxygen typically gains two electrons to become the oxide ion (O2-).
Can nitrous oxide form polyatomic ions?
No, nitrous oxide (N2O) does not form polyatomic ions. Nitrous oxide exists as individual molecules composed of two nitrogen atoms and one oxygen atom, and it does not gain or lose electrons to form polyatomic ions.
What is the reaction between zinc oxide and ammonium chloride on heating?
ZnO + 2 NH4Cl = ZnCl2 + 2 NH3 + H2O The oxide ion reacts as a strong base with the ammonium ion, a weak acid to generate ammonia and water. In this reaction, the zinc and chloride ions act as 'spectator ions'.
Why chloride and oxide form negative ions?
those elements on the periodic table belong to the same category which makes them -ions
Describe the structure of sodium chloride and magnesium oxide as solids?
Sodium chloride has a crystalline structure where each sodium ion is surrounded by six chloride ions and vice versa. Magnesium oxide has a three-dimensional lattice structure in which magnesium ions are surrounded by oxygen ions and vice versa.
What element combined with chloride ion would form an ionic compound?
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
What does zinc oxide with hydrochloric acid make?
When zinc oxide reacts with hydrochloric acid, it forms zinc chloride and water. This is a typical acid-base reaction in which the hydroxide ions from the zinc oxide react with the hydrogen ions from the hydrochloric acid to form water.
What happen to the ferric oxide sol when sodium chloride is added?
The color of the fe2o3 became light when sodium chloride was added. Adding an electrolyte solution introduces oppositely charged ions that neutralize the surface charges of the particles which allow the particles to coagulate and settle.
What are the products of sodium chloride and hydrogen oxide?
The sodium chloride simply separates into ions: Na+ and Cl-
Which element reacts to form oxide ions?
Oxygen is the element that reacts to form oxide ions. Oxygen typically gains two electrons to become the oxide ion (O2-).
What is calcium ions and chloride ions formula?
The ions should form CaCl2 because the two chlorine atoms each take an electron from calcium to form the chloride ion Cl-, and the calcium becomes Ca2+ ion.
Can nitrous oxide form polyatomic ions?
No, nitrous oxide (N2O) does not form polyatomic ions. Nitrous oxide exists as individual molecules composed of two nitrogen atoms and one oxygen atom, and it does not gain or lose electrons to form polyatomic ions.
What is the reaction between zinc oxide and ammonium chloride on heating?
ZnO + 2 NH4Cl = ZnCl2 + 2 NH3 + H2O The oxide ion reacts as a strong base with the ammonium ion, a weak acid to generate ammonia and water. In this reaction, the zinc and chloride ions act as 'spectator ions'.
What is the test to show if hydrogen chloride contains chloride ions?
Add silver nitrate to it. Silver chloride which is. A white ppt will form. This shows that chloride ion is present.
What kind ions will chloride form?
Chloride will typically form negatively charged ions called chloride ions, written as Cl-. These ions are formed when chlorine gains an extra electron to achieve a full outer electron shell, giving them a charge of -1.
