PPT-Describe the arrangement of ions in a giant ionic structure

The ions are arranged in a lattice There is attractive electrostatic forces between the ions which are very strong eg sodium chloride ionic lattices Give two properties of giant ionic structures .

Ionic (i.e. salt) refers to +ve ion plus -ve ion. Usually this is a metal + non-metal or metal + polyatomic ion (e.g. NaCl, NaClO. SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . 1). 2). 3). 4). Group 7.

What is the atmosphere?. Dry air is a mixture of gases. Our atmosphere is made up of the following:. 78% Nitrogen. 21% Oxygen. 1% Argon. 0.04% Carbon Dioxide . Chemicals of air consists of atoms and small molecules. There are weak forces of attraction between the molecules so these chemicals have low melting and low boiling points..
