There's growing evidence ...Fentanyl (or hydromorphone) have a better side effect profile than morphine (remember the vaunted vasodilation is only a side effect) thereby making fentanyl a better choice..
The subatomic particles in the nucleus of a carbon atom are protons and neutrons. The atomic nucleus contains protons and usually neutrons (except for hydrogen-1 (protium) atoms. The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number #6#. So all atoms of carbon have #6# protons in their atomic nuclei.
electron is located in atom outside the nucleus. They are responsible for electricity. electrons are located in the outer part of the atom, with the neutrons and protons located in the center (the nucleus) mass:9.10938215(45) Ã 10â31 kg or 1/1836 of the proton radius:2.8179 Ã 10â15 m.
