How many lead ions surround each sulfide ion?
18
What does it mean to say that the ions of an electrolyte behave independently of one another when the electrolyte is dissolved in water?
When an electrolyte dissolves in water, its ions dissociate. This means that the ions are separated. Although they are still in direct proportions with one another (mass wise), unless they are precipitated out of solution, they will remain separate from each other
The process whereby water molecules surround ions during the process of dissolving is called?
The process whereby water molecules surround ions during the process of dissolving is called hydration. This occurs when water molecules interact with and surround the charged particles of an ionic compound, breaking the ionic bonds and allowing the compound to dissolve in water.
If the pattern of ions shown here for galena is expanded in every direction how many sulfide ions would sorround each lead ion?
In galena (PbS), the structure consists of lead ions (Pb²⁺) surrounded by sulfide ions (S²⁻). Each lead ion is coordinated by four sulfide ions in a tetrahedral geometry. Therefore, if the pattern is expanded in every direction, each lead ion will still be surrounded by four sulfide ions.
What do like charged ions do?
Like-charged ions repel each other. Opposite-charged ions attract each other.
How many lead ions surround each sulfide ion?
18
What ions most closely surround each chlorine ion?
positively charged cations surround each chlorine ion the most closely
How many sulfide ions are would surround each lead ion?
Each lead ion would be surrounded by six sulfide ions. This arrangement is based on the coordination number of lead, which is typically 6 in the formation of lead sulfide (PbS) crystal lattice.
If the pattern of ions shown here for galena is expanded in every directionhow many sulfide ions would surround each lead ion?
Each lead ion would be surrounded by six sulfide ions in a cubic closest packing arrangement, which is the most efficient way for spheres to pack together. In this arrangement, each sphere is surrounded by six other spheres.
How many ions of chlorine surround each ion of sodium?
In a sodium chloride crystal, each sodium ion is surrounded by six chloride ions, and each chloride ion is surrounded by six sodium ions. This results in a 1:1 ratio of sodium ions to chloride ions in the crystal lattice.
How many sulfide ions would surround each lead ion?

What is the process called when water molecules surround ions during the process of dissolving?
The process is called hydration. Water molecules surround ions and form a hydration shell, which helps in the dissolution of the ions in water.
When a salt crystal is dropped into water the water molecules are attracted to the salt's ions and will surround them What is this called?
This process is called dissolution. Water molecules surround the individual ions of the salt crystal, separating them from the crystal and forming a solution.
MgO has the same crystal structure as NaCl face-centered cubic How many oxide ions surround each Mg2 plus ion as nearest neighbors?
Each magnesium ion in MgO is surrounded by six oxide ions as nearest neighbors in a face-centered cubic crystal structure.
What does it mean to say that the ions of an electrolyte behave independently of one another when the electrolyte is dissolved in water?
When an electrolyte dissolves in water, its ions dissociate. This means that the ions are separated. Although they are still in direct proportions with one another (mass wise), unless they are precipitated out of solution, they will remain separate from each other
How many potassium ions and iodine ions would be needed to make a neutral compound?
One of each K+ + I- -----> KI.
The process whereby water molecules surround ions during the process of dissolving is called?
The process whereby water molecules surround ions during the process of dissolving is called hydration. This occurs when water molecules interact with and surround the charged particles of an ionic compound, breaking the ionic bonds and allowing the compound to dissolve in water.
