Formulas of Six Salts Formed by Elements of the 3rd Period

The 3rd period of the periodic table consists of elements from sodium (Na) to argon (Ar). These elements can form various salts when combined with other elements. Here are the formulas of six salts formed by elements of the 3rd period:

1. Sodium Chloride (NaCl): Sodium chloride is a common salt that forms when sodium (Na) reacts with chlorine (Cl). Its chemical formula is NaCl.

2. Magnesium Oxide (MgO): Magnesium oxide is formed when magnesium (Mg) reacts with oxygen (O). Its chemical formula is MgO.

3. Aluminum Nitrate (Al(NO3)3): Aluminum nitrate is a salt formed by the reaction of aluminum (Al) with nitric acid (HNO3). Its chemical formula is Al(NO3)3.

4. Silicon Dioxide (SiO2): Silicon dioxide, also known as silica, is formed when silicon (Si) reacts with oxygen (O). Its chemical formula is SiO2.

5. Phosphorus Pentachloride (PCl5): Phosphorus pentachloride is a compound formed by the reaction of phosphorus (P) with chlorine (Cl). Its chemical formula is PCl5.

6. Sulfur Hexafluoride (SF6): Sulfur hexafluoride is formed when sulfur (S) reacts with fluorine (F). Its chemical formula is SF6.

These are just a few examples of salts formed by elements of the 3rd period. There are many more possible combinations and compounds that can be formed by these elements.
