Periodic Table Elements Name
What is the 118 elements name?
Related Topics – Also, check ⇒ 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 nucleus of an atom. 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. Put your understanding of this concept to test by answering a few MCQs.

How are periodic elements named?
Profusion of naming conventions – Because discovering an element can be a difficult task, individuals or groups that discover an element typically get the privilege of naming it. Elements have been named after a number of things including their attributes, the compound or ore from which they were isolated, how they were discovered or obtained, mythological figures, places, and famous people.
Some elements have descriptive names based on an attribute of the element. For example, some types of phosphorous burn when exposed to air. The Greek phosphoros, from which the name phosphorous is derived, means “lightning bringer” representing its reactivity. Iodine is named from the Greek word iodes, which means “violet” because of the purple color of the gaseous form of iodine.
Other elements were named after the compound or ore from which they were isolated. For example, aluminum is found in alum (a compound of aluminum potassium and sulfate) and was named after that compound. Nickel was named after the German word kupfernickel (or kopparnickel ) meaning “copper colored” which is descriptive of the ore, niccolite (or nickeline), from which nickel is obtained.
- Like helium and technetium, some of the elements were named based on how they were discovered or how they were obtained.
- Scientists discovered helium when they were studying a solar eclipse and saw an unexpected line in an emission spectrum; therefore, helium was named after the Greek word for the sun, helios,
Technetium is named from the Greek word technªtos, which means “artificial” and is applicable because technetium has no stable isotopes and scientists produced it artificially in a laboratory. Scientists named the elements uranium, neptunium, and plutonium after planets.
In 1789, they named element 92, uranium, after Uranus, discovered in 1781. When elements 93 and 94 were discovered in the 1940s, scientists named them neptunium and plutonium after the planets that followed Uranus in the solar system. Scientists also named elements 46 (palladium) and 58 (cerium) after heavenly bodies, but in these instances after the asteroids Pallas and Ceres, respectively.
Still other elements were named after mythological figures. Thorium derives its name from Thor, the Norse god of thunder. Element 73, tantalum, gets its name from Tantalus, a Greek god and son of Zeus. Tantalus is best known for his eternal punishment, which was to suffer unquenchable thirst.
Forced to stand in a pool of water, when Tantalus bent down to drink the water would disappear. Scientists chose this name for tantalum because its oxide is unreactive with acid, a metaphorical parallel to Tantalus’s fate. Later, when scientists discovered that one of the first samples containing tantalum also contained another new element, it was named niobium after Niobe, Tantalus’s daughter.
More recently discovered elements have names that represent places. Scientists named the elements yttrium (Y), ytterbium (Yb), terbium (Tb), and erbium (Er) for Ytterby, Sweden, as they were all found there in a mine. Scientists named berkelium (Bk) in honor of Berkeley, CA, where this element was discovered.

Who named elements?
Known elements – All 118 discovered elements are confirmed and have a formal name and symbol, as decided by IUPAC, The last four names and symbols were added on November 28, 2016. Currently there are no unconfirmed discoveries and all seven periods (rows) of the periodic table are completed.
How many elements are there?
Periodic table – The properties of the chemical elements are often summarized using the periodic table, which powerfully and elegantly organizes the elements by increasing atomic number into rows ( “periods” ) in which the columns ( “groups” ) share recurring (“periodic”) physical and chemical properties.
- The current standard table contains 118 confirmed elements as of 2021.
- Although earlier precursors to this presentation exist, its invention is generally credited to the Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring trends in the properties of the elements.
- The layout of the table has been refined and extended over time as new elements have been discovered and new theoretical models have been developed to explain chemical behavior.
Use of the periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior. The table has also found wide application in physics, geology, biology, materials science, engineering, agriculture, medicine, nutrition, environmental health, and astronomy,
