When a metal (usually 1, 2 or 3 electrons in outermost shell) reacts with a non-metal (usually 5, 6 or 7 electrons in outermost shell), transfer of electrons takes place from metal atoms to the non-metal atoms and an ionic bond is formed. When a metal reacts with a non-metal, electrons transfer from the metal to the non-metal. Whether a metal burns in air or oxygen depends on exactly what form it is in (a large chunk, or a fine powder, for example) and how reactive it is. 19. - Many elements react with oxygen through burning to form a group of compounds called oxides.
