Metals bond to each other via metallic bonding, Electricity can flow via free or delocalized electrons. If they are only given some energy, but not enough to knock them loose, they will move from one orbital to another (say from the S-orbital to the P-orbital). In most substances, the electrons remain within their comfortable environments (stablest energy configuration) without expressing any wanderlust or delocalization. 8 What are the electronegativities of a metal atom? Metals conduct electricity by allowing free electrons to move between the atoms. The delocalization produces what is called a resonance structure . The "holes" left behind by these electrons are filled by other electrons coming in behind them from further back in the circuit. When electricity flows, the electrons are considered "free" only because there are more electrons than there should be, and because the transition metals, such as iron, copper, lead, zinc, aluminum, gold etc. Because of its alloy structure, stainless steel is a poor conductor. When a bond forms, some of the orbitals will fill up with electrons from the isolated atoms depending on the relative energy levels. 1 Why are electrons in metals delocalized?

The valence electrons in the outermost orbit of an atom, get excited on availability of energy. As a result, the bond lengths in benzene are all the same, giving this molecule extra stability. These delocalised electrons can all move along together making graphite a good electrical conductor. Delocalization occurs when a pair appears in one place in one form and another place in another form. Localized orbitals may then be found as linear combinations of the delocalized orbitals, given by an appropriate unitary transformation. https://www.youtube.com/watch?v=bHIhgxav9LY. D. Atomic orbitals overlap to form molecular orbitals in which all electrons of the atoms travel. answer choices They don't Which combination of factors is most suitable for increasing the electrical conductivity of metals? "Metals conduct electricity as they have free electrons that act as charge carriers. In insulators, the orbitals bands making up the bonds are completely full and the next set of fillable orbitals are sufficiently higher in energy that electrons are not easily excited into them, so they can't flow around. The greater the number of electrons in the sea, the greater would the ability of metals to conduct electricity.
