The periodic table of elements is widely used in the field of Chemistry to look up chemical elements as they are arranged in a manner that displays periodic trends in the chemical properties of the elements. However, the Periodic table generally displays only the symbol of the element and not its entire name.
Most of the symbols are similar to the name of the element but some symbols of elements have Latin roots. An example for this is silver which denoted by Ag from its Latin name “Argentum”. Another such example would be the symbol ‘Fe’ which is used to denote Iron and can be traced to the Latin word for iron, “Ferrum”. It could prove difficult for a beginner in chemistry to learn the names of all the elements in the periodic table because these symbols do not always correspond to the English names of the elements. Therefore, a list of 118 elements and their symbols and atomic numbers is provided below:

Frequently Asked Questions on 118 Elements and Their Symbols and Atomic Numbers
How many elements are there in the periodic table?
Currently, there are 118 elements in the periodic table.
Define Atomic Number.
A chemical element’s atomic number is the number of protons in the nucleus of an atom of the element. It is the nucleus’ charge number because neutrons have no net electrical charge. The atomic number of an element determines its identity as well as many of its chemical properties. The modern periodic table is arranged in ascending order of atomic number.
What is the relationship between Atomic numbers and Chemical Properties?
The atomic number determines an element’s chemical properties because the number of protons in an electrically neutral atom also determines the number of electrons. This, in turn, determines the atom’s electron configuration and the nature of its outermost or valence shell. The valence shell’s behaviour determines how easily an atom forms chemical bonds and participates in chemical reactions.
Define chemical symbol.
A chemical symbol is an abbreviation used to represent an element or an atom of an element. For example, H is the chemical symbol for the element hydrogen, Cl is the atomic symbol for chlorine, Fe is the chemical symbol for iron and so on.
How do you write chemical symbols?
Some symbols are derived from the element’s common name, while others are abbreviations of the element’s name in another language. The majority of symbols consist of one or two letters, but three-letter symbols have been used to describe some elements with atomic numbers greater than 112.
Only the first letter of a symbol is capitalised to avoid confusion with other notations. For example, Co is the symbol for the element cobalt, but CO is the notation for the compound carbon monoxide, which contains carbon (C) and oxygen (O) atoms.

Is there any other name of oganesson
As per the IUPAC guidelines for the nomenclature of elements with atomic number greater than 100, the alternate name for Oganesson is ‘ununoctium’.
Thank you very much.
