Answer:
magnesium and chlorine
Explanation:
An ionic bond is usually formed between a metal and a nonmetal. An ionic bond involves the transfer of one or more electrons from a highly electro positive metal to a nonmeta.
Usually, the electro negativity difference between the two species involved in an ionic bond is usually high.
For instance, the electro negativity of magnesium is 1.31 while that of chlorine is 3.16. This implies that they have a difference in electro negativity of about 1.85 between them which is large enough to be considered as leading to a pure ionic bond. An electro negativity difference above 1.7 is generally regarded as leading to the formation of an ionic bond.
Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
mark me brainliesttt :))
A chemical change affects on the molecular level of matter, which makes it irreversible. Combustion is a pretty good exmple. Physical changes are reversible and dont alter the formula. Hope this helped!
