Why is carbonate 2 charge

In the carbonate atom nuclei there are therefore 30 positively charged protons. So how many electrons on carbonate? There are 6 from carbon, 24 from oxygen, PLUS 2 extra negatively charged particles from the formal charge on the anion. Of course this assignment of charge is a formalism; and we would distribute the charge over the oxygen centres by resonance. Compared to the number of protons, how many electrons does the carbonate ion have?

Chemistry Ionic Bonds Polyatomic Ions. Dec 19, Explanation: The number of nuclear protons are the number of positively charged particles contained in atomic nuclei. Related questions How do you draw the lewis structure for polyatomic ions? The number of protons are not suppose to be equal to the number of electrons? How come we are How do you calculate the total number of protons and electrons in a polyatomic Ion.

Do you have Lewis structure of carbonate ion is drawn in this tutorial step by step. Total valence electrons concept is used to draw the lewis structure of CO 3 After finishing the lewis structure of CO 3 2- , there should be a -2 charge and it should be stabile structure. You will learn about these facts in this tutorial. Carbonate ion has a -2 charge.

Metal carbonate compounds are common in the world. As an CaCO 3 can be given. Following steps are required to draw the CO 3 2- lewis structure and they are explained in detail in this tutorial.

Drawing correct lewis structure is important to draw resonance structures of CO 3 2- correctly. Carbon is located at group 4 in the periodic table. So, carbon has four electrons in its valence shell.

Oxygen is located at 6 th group. It has six electrons in valence shell. There are -2 charge on CO 3 2- ion. Therefore there are two more electrons which contribute to the valence electrons. Total electron pairs are determined by dividing the number total valence electrons by two. For, CO 3 2- ion, Total pairs of electrons are To be the center atom, ability of having higher valance is important. Carbon has the more chance to be the center atom See the figure because carbon can show valance of 4.

Oxygen's highest valence is 2. So, now we can build a sketch of CO 3 2- ion. After, marking electron pairs on atoms, we should mark charges of each atom.

Marking of charges are significant because it is used to determine the best lewis structure of the ion. In new structure, charges of atoms are reduced than previous structure.
