Determined on basis of baseline platelet count, desired platelet count, and estimated blood volume. For 70 kg patient, 4 x 10 11 platelets (about 4 units WB platelets or 1 apheresis platelet), platelet increment of approximately 30,000/ul is expected in the absence of alloimmunization or excessive consumption.
Zinc has 30 protons. The number of electrons varies, depending on ionization state, and is 30 for the neutral state. The number of neutrons varies, with 30 different isotopes â¦known to exist. 5 are stable, having 34, 36, 37, 38, and 40 neutrons.
Nucleons are either protons or neutrons and the total number of nucleons is given the symbol A (also known as the mass number). The total number of protons within the nucleus is called the atomic number and given the symbol Z.Protons and neutrons have a mass of 1, protons are positively charged and neutrons have no charge. 1  A (mass number): total number of nucleons = protons + neutrons.2  Z (atomic number): number of protons. great many different configurations of the nucleus may occur. In each case, the atomic number defines the element, i.e. it is the number of protons that determines that carbon (having 6 protons) is carbon.
