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 sum of the number of protons and neutrons in the nucleus of an atom is called the mass number (A), or nucleon number. For isotopes of an element, the mass number is always different (because the number of neutrons changes and neutrons contribute to the mass number).or example, the number of protons in any atom of hydrogen is 1, and the number of protons in any atom of helium is 2. The number of protons in the nucleus of an atom is called its atomic number (Z), which identifies the atom.
