Which of the following can conduct an electric current?
Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.
Which of the following will conduct electricity as a solid?
Graphite is a good conductor of heat and electricity.
Can NaCl conduct electricity?
Salt is sodium chloride. … When the sodium chloride dissolves in water, the sodium atoms and chlorine atoms separate under the influence of the water molecules. They’re free to move around in the water as positively and negatively charged ions. This separation of charge allows the solution to conduct electricity.
Can C6H12O6 conduct electricity?
Let’s now go over the compounds listed in answer choices: C3H7OH is a covalent compound (all the elements are nonmetals) and does not conduct electricity, C6H12O6 similarly is a covalent compound because it consists of all nonmetals. … Both of these compounds can conduct electricity.
Can a diamond conduct electricity?
Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point. … It does not conduct electricity as there are no delocalised electrons in the structure.
Which substance is a conductor of electricity?
Copper is the most common material used for electrical wiring . Silver is the best conductor, but it is expensive. Because gold does not corrode, it is used for high-quality surface-to-surface contacts. However, there are also many non-metallic conductors, including graphite, solutions of salts, and all plasmas.
Can solid nabr conduct electricity?
Sodium bromide is an ionic compound. … Therefore, aqueous sodium bromide will conduct electricity, because it dissociates into sodium cations (Na+) , and bromide anions, (Br−) . However, solid sodium chloride will not conduct electricity. Deionized water has no ions, so it will not conduct electricity.
Is NaCl a good conductor of electricity?
The solution of sodium chloride in water is a good conductor of electricity because of the ions that act as the charge carriers. … This difference in electronegativity forms a crystalline solid structure of positively charged sodium ions and negatively charged chloride ions.
Does CA conduct electricity?
Calcium is a metal and metals are good conductors of electricity as they contain mobile electrons.
Does NaCl have free electrons?
Explanation: Solid NaCl maintains a crystalline structure that does not have free electrons as in the lattice structure of metals. … So unlike electron movement in wires, the chemical process does not go on indefinitely.
