The Period 3 elements react with water at varying levels of intensity. When reacting with cold water, the corresponding hydroxide is produced. However, when steam is required to induce a reaction, then an oxide is formed.
Most Period 3 elements can burn in the presence of oxygen, producing different coloured flames and forming the corresponding oxide.
There is no general trend in melting point along Period 3. The melting point is determined by the strength of the intermolecular interactions between the neutral molecular forms of the elements.
Period 3 elements react with steam to form oxides. These oxides can then undergo further reactions with water to form acids or bases
