Juli 2024 · When electrons from the electric source (battery) come along, lattice electrons are pushed out. Metals continue to do so (conduct electricity) until the lattice electrons are being replaced, not removed. Chemical bonding The atoms of the elements are bonded together by ionic, covalent, and coordinate (dative) covalent bonds.
