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...

Answers. Best Answer: ionic compounds always form from metals and nonmetals. thats what makes them an ionic compound. the metals have a postive charge and need more electrons to be neutral, while the nonmetals have a negative charge and need more protons to be neutral. So the metal and nonmetal combine having a net charge of 0 to make an ionic compound.
