British chemist John Newlands
was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves.

How did Dmitri Mendeleev create the periodic table?
On 17 February 1869, Russian chemist Dmitri Mendeleev
jotted down the symbols for the chemical elements
, putting them in order according to their atomic weights and inventing the periodic table. … It was perhaps the greatest breakthrough in the history of chemistry.
What elements are named after scientists?
Many elements were named after famous scientists. Some of the best-known elements include
einsteinium
(Albert Einstein), curium (Marie and Pierre Curie), rutherfordium (Ernest Rutherford), nobelium (Alfred Nobel), and mendelevium (Dmitri Mendeleev).
Who is known as father of periodic table?
Dmitri Mendeleev
, Russian in full Dmitry Ivanovich Mendeleyev, (born January 27 (February 8, New Style), 1834, Tobolsk, Siberia, Russian Empire—died January 20 (February 2), 1907, St. Petersburg, Russia), Russian chemist who developed the periodic classification of the elements.
How did the periodic table get its name?
Why is it called the Periodic Table? It is called “periodic”
because elements are lined up in cycles or periods
. From left to right elements are lined up in rows based on their atomic number (the number of protons in their nucleus).
What is the name of elements 89 103?
actinoid element
, also called actinide element, any of a series of 15 consecutive chemical elements in the periodic table from actinium to lawrencium (atomic numbers 89–103).
What was wrong with Mendeleev’s periodic table?
In devising his table,
Mendeleev did not conform completely to the order of atomic mass
. He swapped some elements around. (We now know that the elements in the periodic table are not all in atomic mass order.)
Which is Eka Aluminium?
Eka-aluminium was the name given by Mendeleev to the undiscovered element which now exists by the name of
Gallium
. Gallium belongs to group 13 of the periodic table. Its atomic number is 31 with the symbol Ga . It is a soft, silvery metal at standard temperature and pressure.
Can you now say why Mendeleev?
Mendeleev
developed a Periodic Table of elements
wherein the elements were arranged on the basis of their atomic mass and also on the similarity on chemical properties. … On this basis he formulated a Periodic Law, which states that ‘the properties of elements are the periodic function of their atomic masses’.
Who named the elements?
Many countries have adopted the element names that have been agreed upon by the International Union of Pure and Applied Chemistry (IUPAC). According to the IUPAC, “elements can be named
after a mythological concept
, a mineral, a place or country, a property, or a scientist”.
Is indium named after India?
They named the element indium, from the indigo color seen in its spectrum, after the Latin indicum,
meaning ‘of India
‘.
What element is named after a female scientist?
Four of those elements are named in tribute to the village (ytterbium, erbium, terbium, yttrium). 15 are named after scientists, only two of whom were women: Marie Curie and Lise Meitner are immortalised in
curium and meitnerium
.
Who found water?
Who discovered the water? It was
the chemist Henry Cavendish
(1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
