Metals like Copper and Aluminum are good conductors of heat and electricity. How would you explain this property of metals?
It is due to the electrons located on the surface of metallic element
It is because metals have lesser number of protons inside the nucleus.
It is due to the position of the atoms in the lattice that allows planes of cations to slide past each other.
d. It is because metals consist of sea of free-flowing electrons that allows the
energy to transfer from one atom to another. ​
