Explain why metals such as iron and gold are good conductors of electricity.There is a strong electrostatic attraction between the metal ion and the delocalised electrons.The delocalised electrons are free to move around and carry an electrical charge.The metal atoms are arranged in layers and can slide over each other.Metals like iron and gold are malleable.

Which one of the following is the reason why pure metals are good electrical conductors?The movement of delocalised electrons.The arrangement of metal atoms in layers.The strong force of attraction between metal ion and delocalised electron.The high melting and boiling points.

Why are metals typically good conductors of electricity? Question 15 options: Their unit cells allow for the easy movement of electrons Their color allows for the easy movement of electrons Their weight helps conduct electricity

Metallic bonding always occurs between:Noble gasesMetal atomsNon-metal atomsMetal and non-metal atoms2A metallic bond is the electrostatic attraction between:Positive ions and delocalised electronsNegative ions and delocalised electronsElectrons and delocalised negative ionsElectrons and delocalised positive ions3Which of these is a property of metals?Poor conductors of electricityLow boiling pointsMalleableLow melting points4Which of the following statements best describes why metals are good conductors of heat?Metallic bonds are very strongLayers of metal atoms can slide past one another easilyMetals have high melting pointsThe delocalised electrons can carry thermal energy through the substance5Which of the following is a metal alloy?AluminiumCopperSteelIron6Metal alloys are generally harder and stronger than the individual elements they are made from. This is because the atoms of each element are of a different size and therefore:Disrupt the regular layers of ions, making them less malleableIncrease the size of the latticeLead to an increase in boiling pointLead to an decrease in boiling point

Metals are materials that are low in electrical resistivity. What does it tells about the nature of metals as conductor?Group of answer choicesMetals are not good conductors.Metals are bad electrical conductors of current because it has a low electrical resistivity.Metals are bad electrical conductors of current because it has a high electrical conductivity.Metals are good electrical conductors of current because it has a high electrical conductivity.

Assertion (A): The metals and alloys are good conductors of electricity Reason (R) : Bronze is an alloy of copper and tin and it is not a good conductor of electricity.
