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...

1 An ionic compound is a collection of an equal number of positive and negative ions arranged in a three-dimensional lattice. 2  Ionic compounds can be dissociated into their constituent ions with little effort. 3  Further they can be electrolyzed to produce elements or covalent molecules of the constituent atoms.
