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...

] forces of attraction between oppositely charged ions. Positively charged Na ions and negatively charged Cl ions. The oppositely charged ions are arranged in a regular way to form giant ionic lattices lattice: A lattice is a regular grid-like arrangement of atoms in a material. . Ionic compounds compounds: Substances formed by the chemical union (involving bond formation) of two or more elements. often form crystals as a result.
