Why do metals giant covalent structures not conduct electricity?
Because there are no free electrons. However, graphite does conduct electricity as there are free electrons.
Do ionically bonded materials conduct electricity?
Yes, in either the molten state or in solution
Do materials with ionic bonds conduct electricity in a solid and liquid state?
Materials with ionic bonds normally conduct electricity only in a liquid state. However metals, which have what are sometimes called "delocalized" ionic bonds, also conduct electricity in the solid state. It is now customary to consider metallic bonds a separate class from both ionic and covalent bonds.
Materials with bonds conduct electricity in the solid state while those with bonds conduct electricity only when melted or dissolved in water?
metallic, ionic
Can ammonia conduct electricity?
Ammonia is a gas. Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators. "Electricity" requires the movement of electrons. In a gas, these electrons are too dispersed to provided any measurable current.
What are crystalline structures that conduct electricity without resistance when cooled to a certain temperature?
Superconducting materials.
Why do some metals conduct heat better than others?
The ability for a metal to conduct heat depends on how the atoms are aligned. Different materials have different bond structures.
What is the leaf structures?
The structure of a leaf is skeletal
What do we Materials that do not conduct electricity?
Materials that do not conduct electricity are an insulator.
What materials will not carry or conduct electricity?
Insulator materials will not carry or conduct electricity.
What are the structures of a leaf?
epidermisveinscuticlepalisade cells
Why do materials that conduct heat also conduct electricity?
copper, metals...
What are the root like structures of a nerve that receive impulses and conduct them to the cell body?
The dendrites are the root-like structures of a nerve that receive electrical impulses The dendrites then conduct the impulse to the cell body. Dendrites are root-like structures of a nerve cell that receive impulses and conduct them to the cell body.
What materials conduct heat and which do no?
the materials like metal(which have free electrons) conduct heat and light both and those materials which are formed by covalent bond (do not have free electrons) generaly non metals do not conduct heat and electricity.
What materials were used in traditional SA structures?
Materials for traditional structures are usually local materials. In some parts of the world the materials may be Ice, Goat Hide, Tree Branches.
What is the leaf like structures at the base of a flower?
Sepals
Through which structures does transpiration take place?
in the leaf.
