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).
Explain why ionic compounds do not conduct electricity in their crystalline form. Electricity can only be conducted when ions are freely moving in separate positive and negative charges (as in the aqueous form and molten form). In their crystalline form, the ions in the ionic compound are locked tightly in one place and the positive and negative balance out to make the overall structure neutral.
