Explanation When one atom loses an electron to form a cation and another atom gains that electron to form an anion, the resulting attraction between the oppositely charged ions is an ionic bond. This type of bond is typically formed between a metal and a nonmetal, and is characterized by a transfer of electrons rather than a sharing of electrons (as in covalent bonds).
وراثتی حالت جو خون کے ہیموگلوبن کو متاثر کرتی ہے جسے _____ کہا جاتا ہے؟
