What type of bond willform between the metal and nonmetal atoms and why does this bond form

Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.

Explanation:

Ionic Bond.

Explanation:

An ionic bond is a bond in which a metal loses its electrons to the nonmetal that's taking part in the bond. The metal ends up becoming positively charged while the nonmetal becomes negatively charged. This bond forms because metals usually have less than 5 valence electrons, making it so that they'd rather lose these valence electrons rather than gain more to have a full outermost electron orbital. On the other hand, nonmetals tend to have more than 5, so it takes them less energy to gain these last couple of electrons for a complete outermost electron orbital. Therefore, these two bond in an ionic way so that they can both fulfill the needs of the other atom.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
