This quiz contains 9 questions from a mix of 1 subtopics.
positive / negative / electrostatic / ionic / covalent
Metals normally form ions which have a charge, while non-metals form ions with a charge.
Ions are attracted to other ions with the opposite charge, due to forces.
|
Ionic structures involve many ions bonded together via bonds.
The solid arranges itself into a regular 3D structure known as a la.
|
Select three properties that ionic compounds have:
Low melting and boiling points
High strength bonds
High melting and boiling points
Weak strength bonds
Conduct electricity when liquid
Conduct electricity when solid
|
Why can ionic compounds only conduct electricity when in liquid/molten, or aqueous form?
Water is required to conduct electricity
The negative ions can approach other negative ions
Solid ionic compounds do not contain charged particles
The ions are free to move and carry charge
|
strong / weak / high / low / energy / water
Ionic compounds have relatively melting and boiling points.
This is because ionic bonds are very , and a high amount of is required to break the bonds.

Select the correct formula for the ionic compound potassium chloride:
KCl
K2Cl
NaCl
KCl2
|
Select the correct formula for a nitrate ion:
NO3
NO3+
NO3-
N3-
|
Potassium ions and carbonate ions can form an ionic compound.
Potassium ions have a + charge, while carbonate ions have a - charge.
This means every carbonate ion will ionically bond with potassium ions.

What is the chemical formula for the compound calcium sulfate?
CaSO4
Ca(SO4)2
CaSO42+
Ca2SO4
