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.
What is a Carbon Dioxide Molecule? Oxygen and carbon are both non-metals. An oxygen atom has 6 electrons in its outer shell. Oxygen is in group 6 of the periodic table. A carbon atom has 4 electrons in its outer shell. Carbon is in group 4 of the periodic table. Two oxygen atoms and 1 carbon atom will each share two electrons to form four covalent bonds and make a carbon dioxide molecule (CO 2). This is a picture of a carbon dioxide molecule. By sharing the four electrons where the shells touch each oxygen and carbon atom can count 8 electrons in its outer shell. These full outer shells with their shared electrons are now stable, and the CO 2 molecule will not react further with other oxygen or carbon atoms. Each electron pair is one bond.
