Based on the transfer of electrons: Oxidation involves the loss of electrons, while reduction involves the gain of electrons. By reaction type: Redox reactions can be classified as combination, decomposition, displacement, or disproportionation reactions. According to the nature of the reacting species: Redox reactions can involve metal-metal, metal-nonmetal, nonmetal-nonmetal, or organic species.
The element that can exhibit properties of both a metal and a nonmetal is called metalloid. Examples include silicon, germanium, and arsenic. Metalloids have properties that are intermediate between metals and nonmetals.
metalloids
Nails are metal.
When a nonmetal and a metal bond, the nonmetal gains electrons from the metal to form an ionic bond. The nonmetal becomes negatively charged (anion) and the metal becomes positively charged (cation), resulting in an electrostatic attraction between the two ions.
Metal - metal compounds don't exist... Only metal-nonmetal and nonmetal-nonmetal

it is bonding that occurs between a metal and a nonmetal with a transfer of electrons

I think you mean displacement reactions. There are 2 types of displacement reactions: single, and double displacement. Single displacement is when a metal -nonmetal reacts with a metal or a nonmetal atom, and the metal or nonmetal atom switches places with the one in the molecule. Double displacement is when two molecules (same as above) react, and the metals/nonmetals (it doesn't really matter in this case) are swapped. They both have a switching of places between atoms, so I guess this is how they are similar.
a covalent bond is a bond between two nonmetals. the electrons are "shared" between the two atoms. example: H2O. an ionic bond forms between a metal and nonmetal. in an ionic bond, the electrons aren't shared, but are transferred from the metal to the nonmetal, leaving the metal with a positive charge and the nonmetal with a negative charge. examples: MgO, NaCl.
none of the above. a flame is a series of chemical reactions.
