Answer and Explanation: Our answer choices in this question are the metals mercury and nickel and the nonmetals iodine and sulfur.
Which element is probably a good conductor of electricity?
Silver is the most conductive element, in terms of electrical conductivity. Carbon in the form of diamond is the best thermal conductor (silver is the best metal). After silver, copper is the next best conductor, followed by gold. In general, metals are the best thermal and electrical conductors.
Which of the following is a good conductor of electricity a iodine B silver C chlorine and sulphur?
Therefore, graphite is a good conductor of electricity. Hence, the correct answer is option B. Note: The other options- iodine, sulphur and bromine are non-metals.
Is sulfur a good conductor of electricity?
Sulphur is a non metal. It has the properties of poor conductor of both heat and electricity.It is weak,dull and can be easily breakable.
Which element is a solid at STP?
Solids: particles vibrating in a fixed regular geometric pattern. (Crystal lattice structure) Most elements exist as solids at STP. Most metals are solids at STP except for Mercury. Metalloid solids- B, Si, Ge, As, Sb and Te.
Is iodine solid at STP?
Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.
Which of the following is a good conductor?
Good conductors of electricity- gold, silver, copper, aluminum, and graphite. Bad conductors of electricity- plastic, rubber, glass, air, wood, charcoal, and diamond.
What makes a good conductor of electricity?
Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver.
What are 5 good conductors?
The most effective electrical conductors are:
- Silver.
- Gold.
- Copper.
- Aluminum.
- Mercury.
- Steel.
- Iron.
- Seawater.
Is good conductor of electricity bromine iodine graphite sulphur?
Non-metals are the bad conductor of electricity except one i.e Graphite(made of carbon). Hence iodine,sulphur and bromine do not conduct electricity.
Which among the following is a good conductor of electricity and brittle sulphur phosphorus graphite iron?
Graphite is a non-metal and it is a good conductor of electricity.
Is sodium a good conductor of electricity?
Pure sodium (Na) is a good conductor of electricity because the 3s and 3p atomic bands overlap to form partially filled conduction bands.
Is iron a good conductor of electricity?
Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization. Because of this, iron is a good conductor.
Is phosphorus a good conductor of electricity?
Phosphorus is a non-metal. It do not have free electrons for conduction. So, it is bad conductor of electricity.
Is benzene a good conductor of electricity?
No, it is not. In graphite, the -electrons are delocalized over the entire plane of C-atoms, while in a benzene molecule they are only delocalized within the molecule (ring). There is no mechanism in benzene to allow the electrons to hop from one molecule to another.
Which element is a gas at STP?
Gaseous Elements (stp)
The gaseous element group
hydrogen (H), nitogen (N), oxygen (O), fluorine (F), chlorine (Cl) and noble gases helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) are gases at standard temperature and pressure (STP).
Which element is a liquid at STP?
The only elements that are liquids at standard temperature and pressure (aka STP) are Bromine and Mercury.
Which element is a metal that is in the liquid phase at STP?
Key Takeaways: Liquid Elements
They are mercury (a metal) and bromine (a halogen).
Is bromine a solid at STP?
Bromine (Br, element 35), also found as a diatomic molecule (Br2), is a liquid at room temperature, solidifying at -7.2ºC.
Why is fluorine a gas at STP?
As we move from fluorine to iodine, the electrons are further from the nuclei so the electron clouds can more easily distort. The London dispersion forces become progressively stronger. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Can iodine conduct electricity in any state?
Answer: Melting point: Iodine is liquid so it doesn’t have a melting point. Conductor of Eletricity: Iodine does not conduct electricity since each molecule of iodine comprises two iodine atoms joined by a covalent bond that cannot be excited sufficiently to transfer electrical energy.
Which is following is conductor of electricity?
The correct answer is Copper. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.
Which of the following solution is a good conductor of electricity?
Hydrochloric acid is a strong electrolyte and dissociates completely in aqueous solution. The solution contains free mobile ions which allow electric current to pass through it. Hence, hydrochloric acid is a good conductor of electricity.
Is copper a good conductor of electricity?
The lower the level of resistivity, the more electrical conductivity a metal has. And since copper wire has a low level of resistivity, it’s a fantastic electrical conductor.
Is Mercury a good conductor of heat?
Mercury is a bad conductor of heat.
Is copper a conductor?
With the exception of silver, copper is the most common conductive metal and has become the international standard. The International Annealed Copper Standard (IACS) was adopted in 1913 to compare the conductivity of other metals to copper.
