Draw a dot and cross diagram to show the bond present in Sodium Chloride (NaCl). State what type of bonding this is and the type of structure this compound forms.

[draw diagram on the whiteboard]Atoms are most stable when they have the maximum amount of electrons in their outer shell (usually 8)Na is a metal in Group I of the periodic table so it has 1 electron in its outer shell Cl is a non-metal in group 7 of the periodic table so has 7 electrons in its outer shell Na can lose one electron to become Na+, Cl can gain one electron to become Cl-. Electrostatic forces attract the oppositely charged ions together.The type of bonding is IONIC because it is between oppositely charged ions.We would expect this compound to form a giant ionic lattice
