Oxidation State and Numbers of Zn(I2) (Zinc Iodide) To calculate the oxidation numbers for Zn(I2), count the number of atoms, draw the lewis structure by adding bonds, assign electrons from each bond, and count the number of electrons assigned to each atom. Count Atoms Use the chemical...
For a neutralatom, the number of electrons is the same as the number of protons. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in anionif you know its charge. A cation carrie...
To find the number of electrons involved in the electro-deposition of 63.5 g of copper from a solution of copper sulfate, we can follow these steps:Step 1: Determine the molar mass of copper The molar mass of copper (Cu) is giv

Oxidation numbers are the charges associated with an ion. Cations are positively charged, and anions are negatively charged. Most polyatomic ions are negatively charged. The charges result from an excess or deficit of electrons in an atom or molecule. ...
