![]() In order to show how many atoms an element is having in a formula, we have to use the number in subscript. The symbol determines the type of atom or the element. What is a chemical formula?Ī Chemical equation or formula, as described at the beginning of the article, is a symbolic way of displaying the elements and the number of atoms in an element. He was the first scientist who started using symbols for a chemical element. A1, which is an Aluminium atom.Įach element is made of an atomic mass and this was theorized by Dalton. In an equation or a formula, a single atom is denoted by a symbol, i.e. And a symbol is used in writing an equation of a chemical compound as it refers to that particular element. How atom is presented in a formulaĪn element generally has three things, that is its name, its valency, and a symbol. ![]() So an atom is the smallest component of a chemical compound, it is an important part of it. Like there can’t be a wall without the bricks, there can’t be anything without the atoms. The bricks, bound by the mixture of cement and sand, make a wall.īasically, everything in the universe is made of atoms. So if you consider a wall as a compound, a brick can be considered as an atom. ![]() To understand an atom, take an example of a wall. It’s the smallest or the single unit of that makes an element collectively. The lines and symbols are used to from diagrams. If there is an arrow showing two sides, it means the reaction can happen in any of the forward or backward. The formulas also contain the arrows, where one-way arrow denotes the reaction of an element towards the other element. The letters represent the element and the number represents the number of atoms of an element. So it’s like a symbolic presentation of a compound using the letters and numbers.Įach symbol represents an element, and an element is made of atoms bound together by the chemical bond. So if you want to write a compound that shows its elements and their proportions, you have to write it in a formula. Similarly, a compound is made of several elements and an element is made of atoms. For example, Cocoa Butter, Chocolate Liquor, Sugar, Lecithin and a flavoring agent makes a delicious item called Chocolate.
