Systemic scleroderma (systemic sclerosis) - blood vessels and internal organs are also affected (as well as the skin). The patient may experience fatigue (tiredness), weight loss and muscle pains. A risk factor is something which increases the likelihood of developing a condition or disease.
The Atomic number of Carbon is 6. The Atomic mass of Carbon depends on the isotope and may be from 8 to 22. Carbon 12 and Carbon 13 are the only stable isotopes of Carbon. Carâ¦bon 14 is the longest-lived unstable (radioactive) isotope. Only Carbon 12, 13 and 14 are found in nature.
Atomic Number The number of protons always equals the number of electrons in an atom, and that number is equal to the atomic number. For instance, carbon has an atomic number of six and therefore has six protons and six electrons. The Atomic Mass is the weight of an atom and is determined by the number of neutrons and protons that are present in the nucleus. Hope that helps!!!
