Bonding dot and cross diagrams
Did you know?
WebIn a dot and cross diagram, ions are drawn as a central nucleus, surrounded by rings of orbiting electrons ( represented by either dots or crosses ). The formation of ionic molecules can be shown by using dots to represent the electrons of one ion, and crosses for the electrons of another. WebDot and cross diagrams for ionic compounds can be drawn like this: Step 1: Write the chemical symbols of the atoms side by side and draw a ring (the outer shell) around them but keep them separate. They must not overlap like in covalent compounds. Step 2: Fill the outer shell with the correct number of electrons for each atom. NaCl example:
