Type Of Solids - Ionic

Question 1

METALS and NONmetal atoms form?

Answer 1

Ionic solids

Question 2

Ionic solids are made out of what particles?

Answer 2

Positively charged ions (cations) and Negatively charged ions (anions)

Question 3

What are ions held in (structure) and what is the attractive force?

Answer 3

Cations and anions held in a 3D lattice by a STRONG IONIC bond

Question 4

How much energy is required to overcome STRONG IONIC bonds?

Answer 4

Because of the attraction forces of ionic bonds, they require a large amount of energy to overcome THUS melting p/boiling p is high

Question 5

Why WONT ionic solid conduct electricity

Answer 5

Ionic solids DO NOT conduct electricity because they are in a fixed position. Ions CANNOT move so cannot conduct electricity

Question 6

Why can molten/aqueous form of ions conduct electricity

Answer 6

When melted or dissolved in water, the ions are free to move and allows the liquid to conduct electricity

Question 7

Why are ions brittle

Answer 7

Ions are brittle because when it is an IONIC solid, the bonds are directional so they are not malleable nor ductile. Thus making it brittle

Question 8

How do ionic bonds shatter

Answer 8

If Oppositely charged ions forced to shift position= like charges line up and repel, causing crystal to shatter

Question 9

Are ions soluable in water

Answer 9

Ions soluable in water = ions separated from lattice due to attraction to water molecules as it has strong enough to overcome the existing forces between each substance

Question 10

Are non-polar solvents attracted to ions

Answer 10

No. Ie. cyclohexane no attracted to ionic solids thus insoluble
