Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).lood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells.

Ions form electrically neutral compounds because the number of cations (positively charged ions) is equal to the number of anions (negatively charged ions). These ions are held together by strong... Ions form electrically neutral compounds because the number of cations (positively charged ions) is equal to the number of anions (negatively charged ions).
Notice that the properties of ionic compounds relate to how strongly the positive and negative ions attract each other in an ionic bond. 1  Ionic compounds form crystals. 2  Ionic compounds form crystal lattices rather than amorphous solids.
