Learn About Different Types of Chemical Formula

by · Published · Updated

A compound’s chemical formula serves as a visual depiction of the substance’s molecular structure. Understanding chemical formulas may help us better understand the components that make up a mix and the ratios of these components to produce those molecules. According to the H2O chemistry of water, a water molecule is formed by the union of two hydrogens and oxygen.

If you want to succeed in any competitive test, including SSC, you need to have a good grasp of the common names and formulae of chemical compounds. In this post, we’ll cover top tips for writing chemical formulae:

Compound Of Chemical Elements:

Many similar molecules made of atoms from more than one element, bonded together by chemical bonds, make up a molecule-based chemical complex. A certain ratio may determine a chemical compound’s composition. When two hydrogen atoms are joined with an oxygen atom, the result is water (H2O).

To describe the ratio of each element, a chemical formula is often used. A chemical compound may be defined as “a material composed of two or more elements” in the most basic sense. A chemical compound is a mixture of one or more elements.

Chemical Compounds Known by Their Common Names:

Chemical compounds have a scientific name and a common or popular name for each one. A chemical compound’s scientific name is used to identify it by scientists or chemists.

There is a broad term for these things that we use every day, and that name recognises them. As an example, the chemical name of NaCl is Sodium chloride, whereas the popular word is salt.

Inorganic Compound:

An example of a chemical formula is the method in which a chemical compound’s or molecule’s proportions of atoms are presented in terms of chemical element symbols and numbers, and occasionally extra symbols such as parentheses dashed lines, and brackets.

The ratio of atoms per element in a chemical compound is represented by its chemical formula, and subscripts are used to do this. The subscript to the right of each element’s symbol specifies how many atoms are present in the chemical complex.

A chemical formula contains a lot of information about the chemical substance it represents, including the number and kind of atoms it contains and the arrangement of the atoms.

Value of Chemical Formulations:

  • You may deduce a compound’s chemical makeup from its chemical formula, and the ratios of the individual components are also shown.
  • Representation in the chemical equation relies heavily on the compound’s chemical formula.
  • Ions, free radicals, and other chemical species may be represented using chemical equations.

Chemical Formula Types:

A chemical compound’s composition may be described in various ways. As shown in this paragraph, even though the phrase “chemical formula” is common, it can also employ chemical formula(which indicates how many atoms of each component element there are in one molecule of the compound).

Molecular Formula:

The number of components in a substance may be determined by its molecular formula. As in the periodic chart, the elements in molecular formulas are designated by their corresponding symbols; the number of atoms of each molecule component is stated in subscript. C6H12O6 is the molecule’s chemical formula for glucose.

Experimentation-based Formula:

The ratio of the components in a chemical compound is represented by its empirical formula. Experimentation is often used to generate empirical formulas, and CH2O is the molecule’s empirical formula. Based on the molecular formulas, it is possible to develop empirical procedures.

Structural Formula:

Structural formulas, as the name indicates, reveal the arrangement of atoms in a chemical substance.

Writing Chemical Formulas:

A chemical formula must have the symbol for each element, the procedure for each radical, and the valency of each element to be written.

  • When creating a chemical formula, you should consider the following considerations.
  • The vast majority of compounds are two-component systems, meaning they contain just two components. Compounds that have more than two elements are also known.
  • An anion is an atom with a negative charge, whereas a cation has a positive charge.
  • There are two types of compounds: those that include metals and those that contain non-metals. With NaCl as an example, you have Na+ (metal) and Cl– (non-metal) (non-metal ion)
  • It is common for anions with a negative charge of one to have a -ide suffix. When it comes to examples: Floride is a –
  • When an anion has oxyanions (oxygen and another element), the suffix –ate is often used. For instance, SO42- (Sulphate)
  • An anion containing a polyatomic H– ion is given the suffix bi- or hydrogen. It might be HCO3–Bicarbonate or hydrogen carbonate.

Names for several polyatomic anions include:

Chemical Formula Polyatomic Anion
NH2– Amide
PO43- Phosphate
CN– Cyanide

Solved Example:

In one molecule of the substance, determine the number of atoms of each element in each of these chemical formulae.

  • Hydrogen cyanide (HCN) is a very corrosive gas.
  • The painkilling substance codeine is C18H21NO3.
  • Hydroxyapatite, a mineral found in the tooth’s enamel.

Answer:

Hydrogen, carbon, and nitrogen are all made up of one atom apiece. When no subscript is specified, subscript one is understood. According to this formula, a single molecule of the substance consists of 18 C, 21 hydrogen atoms, one N, and three O.

Ten calcium atoms make up the molecule. The subscripts outside the parenthesis alter the phosphorous, hydrogen, and oxygen quantities. As of now, there are six phosphorous and two hydrogen atoms. The formula has two places for oxygen atoms, and OH subunit (21) and PO4 subunit (64) each provide two oxygen atoms, for a total of 26.
