When a chemical's molecular formula is the same as another chemical's molecular formula.
When a chemical's molecular formula is the same as another chemical's molecular formula but it's molecular structure is different.
When a chemical's molecular formula is different than another chemical's molecular formula.

Which of the following best describes the formation of an ionic bond?
Two atoms share their valence electrons equally.
An atom donates its valence electron to another atom, creating ions that attract each other.
Two atoms exchange neutrons to achieve stability.
Electrons are shared unequally between two atoms.
In a covalent bond, what happens to the valence electrons?
They are transferred from one atom to another.
They are shared between atoms.
They are lost to the surrounding environment.
They are used to form ionic bonds.
What is the primary reason ionic compounds are solid at room temperature?
The covalent bonds between the atoms are very strong.
The ionic bonds create a rigid lattice structure that is hard to break.
The molecular bonds are flexible, allowing them to move freely.
Ionic compounds are not solid at room temperature.
Which of the following is a property of ionic compounds?
Low melting and boiling points.
Poor electrical conductivity in solid state.
High melting and boiling points.
Easily vaporized.
Why are ionic compounds typically more brittle than covalent compounds?
The molecular bonds in ionic compounds are very flexible.
The ionic bonds form a rigid lattice that can shatter when stressed.
Covalent bonds are much weaker than ionic bonds.
Ionic compounds are not more brittle; it is the other way around.
Which of the following compounds is likely to have ionic bonds?
CO2 (Carbon dioxide)
NaCl (Sodium chloride)
O2 (Oxygen gas)
CH4 (Methane)
What role do valence electrons play in chemical bonding?
They are irrelevant to the bonding process.
They are the innermost electrons that participate in bonds.
They are the outermost electrons and participate in the formation of chemical bonds.
They stabilize the nucleus during the bonding process.
