- The atomic number of an atom is equivalent to the total number of electrons present in a neutral atom or the total number of protons present in the...
- An element is a substance that can not be decomposed into simpler substances by ordinary chemical processes. It is the fundamental unit of the matter.
- There is a total of 118 elements present in the modern periodic table.
- A chemical symbol is a notation of one or two letters denoting a chemical element. Example: The symbol of chlorine is Cl.
- The first letter is always capitalised for writing the chemical symbol of an element, while the second letter is small.
- Chemical symbols play a crucial role in easing the writing. It is universal, i.e. identical throughout the world.
- The chemical symbol of sodium metal is Na.
- Helium is the smallest atom with a radius of 31 pm, while the caesium is the largest atom with a radius of 298 pm.
- Yes, there is an isotope of the hydrogen atom, protium, which has no neutron.

Elements are arranged in order of increasing atomic number.Elements of the Periodic Table are denoted by a unique symbol and not its entire name, as some elements’ names can be long and complex in nature.Elements are arranged vertically and horizontally. Elements arranged vertically in columns are called ‘Groups’ and elements arranged horizontally in rows are called ‘Periods’.Further elements are grouped as per periodic trends and properties. Example: Elements in group 1A are soft metals that react violently with water.A symbol representing a chemical element is a 'sign' or 'notation' that generally consists of one or two letters. Some symbols have three letters, they generally represent synthesized elements newly, with some being temporarily named like that.
One may ask, ‘How is the symbol of an element derived?’ We can see in the table above that most of the symbols are derived from the elements’ names, by taking either the first or first two letters from the English name of the element. Some symbols of a few elements are derived from their Latin or Greek names. Let us look at some examples: 1. The La...
The first letter of a symbol is capitalized with the second (or third) letters being in lowercase. Example: 'Ca' representing Calcium, 'He' representing Helium, etc. When the symbol representing an element is denoted by one letter only, it is written in uppercase. Example:'N' represents Nitrogen, 'O' represents oxygen, etc. The elements which are n...
In order to achieve the most stable configuration i.e. of a noble gas, the atom of an element tries to gain or lose electrons. This ability of an atom to gain or lose electrons to achieve a stable configuration or inert gas configuration is called the Valency of an element. The number of electrons in the outermost shell is called valence electrons ...
The concept of atomic number and Valency can only be understood if you know what exactly elements are made up of. An element is made up of a single type of atom. An atom is the smallest indivisible unit of matter. It consists of electrons, protons and neutrons. The centre of the atom is also called the nucleus which is positively charged and consis...
Out of all the 118 Elements, 98 Elements are found in nature (those with atomic number 1- Hydrogen 'H' to atomic number 98 – Californium 'Cf'; in the periodic table), with the rest being synthesized from the naturally occurring elements, in a laboratory. Elements synthesized in the laboratory include Einsteinium(99), Fermium (99) and Nobelium (102)...

118 Elements – Their Symbols and Atomic Number. The periodic table is an essential tool widely used by scientists, professionals, teachers, and students of chemistry to find information about chemical elements. It was first developed by Dimitri Mendeleev, who is known as the Father of the Periodic Table.
