What else can I help you with?
What is a substance that contains only one kind of matter called?
A substance that contains only one type of element is referred to as 'intrinsic.' An example being 'Intrinsic Silicon,' used in the production of semi-conductors.
What kind of atoms make up the compound iodine?
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
What are materials that allow electrons to move through them easily?
Materials that allow electrons to move through them easily are called conductors. Common examples of conductors include metals like copper, silver, and gold. The presence of free electrons in the material facilitates the easy flow of electrical current.
Why are metals conductors?
When a metallic element bonds with other metals, their outer electrons are are shared between all the atoms in the metallic lattice. They form a common 'sea' of delocalised electrons attached to no single atom. Because the electrons are free to move, they can carry an electrical current. that is why metals are better conductors
Why do some materials conduct heat better then other?
Materials that conduct heat well typically have closely packed atoms or molecules that allow for efficient transfer of thermal energy through the material. Additionally, materials with free-moving electrons, such as metals, are good conductors of heat as the electrons can easily transfer energy. Conversely, materials with loosely bound atoms or molecules, such as gases and some insulators, are poor conductors of heat.
What kind of material are in most conductors?
Most conductors contain metals. These provide the free electrons, which can pass a current.
What do thermal conductors do?
Thermal conductors allow heat to pass through them easily. They transfer heat from one point to another by the movement of particles such as atoms and electrons. Good thermal conductors include metals like copper and aluminum.
Why are metals good for electrical conductors?
Metal atoms have a few lightly-bound electrons in their outer shells, and these electrons can be easily moved by a modest electrical potential. This makes them good conductors.
Why are there good and poor conductors?
Because different atoms and molecules hold their electrons more or less tightly.
Why are good conductors of heat good conductors of energy?
Heat is energy. You may mean electricity. Atoms larger than Helium have their electrons arranged in layers or shells. It is thought that both heat and electricity travel from atom to atom by moving through the electrons in the outer shell. In good conductors, it is easier for these electrons in the outer shell to move between atoms than it is in other materials. It is thought that electricity or heat moves when an electron moves between atoms.
Why are metals good heat conductors?
Some of the outer electrons of metal atoms are free to move from atom to atom. These free electrons transfer heat readily making metals good thermal conductors.
What kind of solutions have good conductivity?
Solution of electrolytes are good electricity conductors.
How do electrons in conductors move about freely than the electrons in insulators what?
Electrons in conductors, such as metals, are loosely bound to their atoms and can move freely through the material, facilitating the flow of electric current. In contrast, electrons in insulators are tightly bound to their atoms and do not have the ability to move freely, which prevents the flow of electric current. This difference in electron mobility is due to the varying atomic structures and energy band gaps in conductors and insulators. As a result, conductors allow for efficient electron transport, while insulators resist it.
What does heat travel with easily through metals?
Metals are good heat conductors. The electrons are also exicted by thermal energy and that thermal energy rapidly moves to other atoms.
What kind of carbon atoms does a molecule of pentene have?
There is only one (chemical) kind of carbon atoms, they all are alike.
What type of resistance do conductors have?
Conductors have resistance due to collisions between free electrons and atoms within the material. This resistance causes energy to be lost in the form of heat when current flows through the conductor. The resistance value depends on the material and dimensions of the conductor.
What kind of atoms are in a molecule of oxygen?
Oxygen is composed of oxygen atoms.
