not all non metals are good insulators only the solid non-metals
Ionic compounds are good thermal insulators because the strong electrostatic forces between the positively and negatively charged ions restrict their movement, hindering the transfer of thermal energy. This makes it difficult for heat to be conducted through the solid lattice structure of the ionic compound, resulting in low thermal conductivity.
A good thermal insulator has to have tight molecules that dont let heat through good thermal insulators such as
Plastic wood cork tinfoil rubber
Ionic compounds are good thermal insulators mainly due to their strong bonds. Since more energy is needed to break them, they absorb a lot of it before breaking, which creates thermal or heat energy.
Covalent compounds tend to be good insulators - example include fiberglass and ceramic materials. This is because the electrons of the molecules are locked in place and resistent to movement; this tendency insulates the electricity flowing along around them from jumping across the material.
In contrast, ionic compounds tend to be good conductors - examples include salt water and metals. This is because the electrons of the molecules are constantly being exchanged freely between different ions; this tendency allows electricity to flow along the material within impediments.

Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
Cookware needs to have good thermal conductivity, while ionic compounds have poor conductivity. Additionally, ionic compounds are brittle and prone to shattering when subjected to mechanical stress, making them unsuitable for cookware that requires durability and resistance to impact.
Why is cookware not made from ionic compounds?
Cookware is not made from ionic compounds because these compounds tend to be brittle and can crack or shatter when subjected to heat or sudden temperature changes. Metals like stainless steel, aluminum, and cast iron are preferred for making cookware because they have good thermal conductivity and are durable.
Do Ionic compounds have poor or good conductivity?
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
How can molecular compounds be distinguished from ionic compounds?
Molecular compounds are formed by sharing electrons between atoms to create covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another to create ionic bonds. Molecular compounds typically have lower melting and boiling points compared to ionic compounds, which have high melting and boiling points due to strong electrostatic forces between ions. Molecular compounds are typically composed of nonmetals, while ionic compounds are composed of metals and nonmetals.
What elements are good insulators?
Materials with high electrical resistance, such as rubber, glass, and plastic, are good insulators. Non-metals like wood and ceramic also have insulating properties. Additionally, gases like air and vacuum can act as insulators due to their low thermal conductivity.
What are good thermal insulators in buildings?
Common thermal insulators used in buildings include fiberglass, cellulose, foam boards, and spray foam insulation. These materials help reduce heat transfer through walls, ceilings, and floors, improving energy efficiency and reducing heating and cooling costs. It's important to choose the right type of insulation based on factors such as R-value, installation ease, and fire resistance.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are three characteristic properties of iconic compounds?
If you think to ionic compounds:- dissociation in water- good solubility in water- as solids they are insulators- high melting point

What makes good thermal insulators and conductors?
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
Should the ceramic tiles on a shuttle be good thermal conductors?
No. They should be good thermal insulators.
Can you name all the good thermal insulators?
yes
Are good thermal insulators good electrical insulators too?
Not necessarily. While some materials may be good thermal insulators, they may not be good electrical insulators. For example, rubber is a good electrical insulator but not a good thermal insulator. Conversely, materials like glass and ceramic can be both good thermal and electrical insulators.
Is shiny a good insulator?
No, shiny surfaces are not good insulators. Shiny surfaces are reflective and do not support the absorption and retention of heat, which is a characteristic of good insulators. Good insulators are materials with low thermal conductivity that trap heat effectively.
Why is cookware not made from ionic compounds?
Cookware is not made from ionic compounds because these compounds tend to be brittle and can crack or shatter when subjected to heat or sudden temperature changes. Metals like stainless steel, aluminum, and cast iron are preferred for making cookware because they have good thermal conductivity and are durable.
Are napkins insulators?
Napkins are not good insulators, as they are thin and do not provide much thermal or electrical resistance. They are more commonly used for wiping and cleaning purposes.
What matirials are good insulators except foam?
Some other materials that are good insulators are wood, rubber, glass, and fiberglass. These materials have low thermal conductivity, preventing the transfer of heat.
