Carbon dioxide as a non-metallic oxide is acidic. Carbon dioxide reacts with water in a reversible reaction to form carbonic acid (H 2 CO 3). CO 2 (g) + H 2 O (l) H 2 CO 3 (aq). The acid dissociation constant for carbonic acid K a = 4.45 x 10 -7 mol dm -3.arbon dioxide is a simple covalent molecule that most people have heard about, as it is often in the news linked to global warming. Carbon dioxide has the formula CO 2 and at the centre of this linear molecule is a carbon atom joined by two pairs of double-bonds to the oxygen atoms, i.e O=C=O.
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.
