many formulae which ends with ite,ate ide

See your post above.

When it comes to formulas that end with -ite, -ate, and -ide, we are generally referring to chemical compounds. Let's break down each term and understand its meaning:

-ite: This suffix is used to designate an ion or a compound that contains a lower amount of oxygen in comparison to the -ate form. For example, sulfite (SO3 2-) has fewer oxygen atoms compared to sulfate (SO4 2-).

-ate: This suffix is used to indicate an ion or a compound that contains a higher amount of oxygen. For instance, nitrate (NO3-) has more oxygen atoms than nitrite (NO2-).

-ide: This suffix refers to an ion or a compound that doesn't contain any oxygen. It denotes binary compounds, which consist of two elements only. Examples include chloride (Cl-), oxide (O2-), and sulfide (S2-).

To derive the names of compounds, we usually combine the name of the cation (positively charged ion) with the appropriate anion (negatively charged ion) suffix. The cation's name usually remains the same, while the anion suffix varies based on the number of oxygen atoms present.

To determine the chemical formula or name of a specific compound, it's important to know the valency (the combining power) of the elements and the periodic table's information. Consulting a chemistry textbook or utilizing online resources, such as chemical compound databases or formula calculators, can help you find the desired formulas.

If you have a specific compound in mind, please provide more details, and I'll be happy to guide you through the process of finding its formula or name.
