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.
Atoms are made up of three smaller subatomic particles: protons, neutrons, and electrons. Nucleus: the tiny, dense, positively charged center of an atom. â¢protons and neutrons are in the nucleus. â¢makes up over 99.9% of an atomâs mass. â¢if an oxygen atom was as big as a stadium, its nucleus would be the size of a grape.
