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...

Polyatomic ions: Polyatomic ions are electrically charges collections of two or more atoms. Typically in beginning classes people are not expected to predict polyatomic ion formulas. Polyatomic ions usually have a charge because the collection of atoms has either gained an extra electron or else it has lost an electron.Most of the common inorganic polyatomic ions have negative charges.This means the ion has more electrons than the neutral atoms that are in the ion.A polyatomic ion like phosphate, PO43- has three extra electrons beyond the electrons on the P and O atoms.ost of the common inorganic polyatomic ions have negative charges.
