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.
The atomic number, Z, should not be confused with the mass number, A, which is the number of nucleons, the total number of protons and neutrons in the nucleus of an atom. The number of neutrons, N, is known as the neutron number of the atom; thus, A = Z + N (these quantities are always whole numbers).
