metals:
1) have 1-3 electrons in the outer shell of each metal atom
2) lose electrons easily
3) good reducing agents
4) good conductors of heat and electricity
IN metaks electrons are free to move within a fixed array of positive ions, by colliding the electons can transfer heat through the lattice.
non metals:
1) have 4-8 electrons in their outer shell
2) gain or share valence electrons
3) good oxidizing agents
4) poor conductors of heat and electricity
For non metals, there are relatively few free electrons, so the phonon method dominates. A phonon is a quantum of vibrational energy, and by the combination of many phonons, heat is observed macroscopically.
