Substances with many free electrons are good conductors of electricity. Metals like copper and aluminum are examples of materials with many free electrons and are commonly used in electrical wiring due to their ability to easily carry electric current.

What are substances with tightly bound electrons called?
Substances with tightly bound electrons are called insulators. Insulators are materials that do not conduct electricity well because the electrons in their atoms are strongly bound and not easily moved. This contrasts with conductors, like metals, whose electrons are free to move and carry electric current.
Which charges in an atom are more free to move about?
The electrons of an atom can note freely around an atom.
What flows from atom to atom to make electricity?
In metals, electricity flows through the movement of free electrons from atom to atom. These electrons can move easily through the material, creating an electric current.
What are materials with few free electrons called?
such substances are conductors of electricity.
How do electrons help graphite conduct electricity?
In graphite, electrons are delocalized and free to move throughout the material, allowing them to easily carry an electric current. When a voltage is applied, these mobile electrons can flow from atom to atom, making graphite a good conductor of electricity.
How do metallic substances facilitate current flow?
Metallic substances have free electrons, which can move from atom to atom, transferring a charge.
What items transport electricity?
substances which have free electrons present in them are the one's who conduct electricity.These substances have free electrons as there electrons are not held with strong forces by the nuclei and hence get easily excited and come out. so we can say that substances which allow flow of electrons through them are known as conductors.

Can free electrons collide with atoms?
Yes, free electrons can collide with atoms. When a free electron collides with an atom, it can transfer energy to the atom, which may result in ionization or excitation of the atom. These collisions play a significant role in processes like electrical conduction and plasma interactions.
What are materials with few free electrons called?
such substances are conductors of electricity.
What is different between free electron and inner shell electron?
A free electron is able to move as it is in the outer shell of the atom. So free electrons can carry a charge. If an atom has free electrons it is able to conduct electricity. Inner shell electrons cannot carry a charge as they are closer to the nucleus.
An atom with 5 free electrons is said to be?
An atom with 5 free electrons is said to be pentavalent.
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 is the difference between bound and free electrons?
Bound electrons are the electrons locked in orbit of the atom which are held in orbit by its attraction to the positive charge of the proton(s) in the nucleus. Electrons have a negative charge. Conversely, the free electrons are electrons that are not orbiting the nucleus of an atom normally in the form of static electricity. Valence electrons are the electrons orbiting the outermost shell of the atom are weakly held by the positive proton charges and can be transferred to or shared with one or more other atoms. Valence electrons are bound until they are freed by some outside force or reaction.
Does graphite conduct heat and how?
All substances conduct heat to some degree as the heat is transmitted between atom via their vibration in solids. In electrically conductive materials such as metals and graphite, there are delocalised electrons which can pass from atom to atom freely. This is how charged is transmitted to mediate electricity. These flowing electrons can also carry heat and pass it more quickly from atom to atom than through just vibration alone.
