A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...

Use the 3D model and diagrams to help you draw the next row of sodium chloride in a 2D model. In sodium chloride the ions are arranged alternately so, in the next row, chloride ions are located ...

Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl ...
