Compounds Compounds contain more than one kind of atoms (more on atoms, later). It cannot be separated into constituent atoms by simple methods. Eg: common salt (NaCl), Sodium carbonate (Na2CO3). Mixtures Mixtures are a combination of two or more substances, which when combined, each substanc...
Ions form when an atom loses or gains an electrons. Positive ions form when atoms lose electrons and Negative ions form atoms gain electrons. Describe the structure of an ionic compund Ionic compounds have a giant ionic lattice structures. The ions form closely packed regular lattice and they ...
