Copper has Cu2+ atoms arranged in layers and held together by a sea of electrons in lattice form. The sea of electrons or de-localized electrons are provided by Cu. Each copper atom contributes 2 electrons to the sea for binding of Cu2+ atom layer.
The sea of electrons are highly mobile and require a very small potential difference across the atoms to push these electrons to form a current. The mobility, ease and freeness of these electrons allows copper to be a good electrical conductor
b. the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “cloud” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
c. due to the presence of free electrons in its outer energy levels
Car with a mass of 1210 kg moving at a velocity of 51 m/s. 2. What velocity must a 1340 kg car have in order to have the same momentum as a 2680 kg truck traveling at a velocity of 15 m/s to the west? 3.0 X 10^1 m/s to the west.
