It is called the periodic table of the elements. The sequence begins with hydrogen (at the center of the spiral), which is the first and simplest element.

That said, the periodic table of elements is nothing new. The Russian chemist, Dmitri Mendeleev, first designed the periodic table of elements in 1869, nearly 150 years ago.

It is the arrangement of these electron orbits that is reflected in the different blocks of the periodic table. The table we know today is a descendant of that invented in 1869 by a wild-haired ...

2019 is the International Year of the Periodic Table. The person who typically gets credit for its creation is Dimitri Mendeleev. But there were many more chemists who should be recognized.

While only 63 elements were known in Mendeleev’s time, today’s periodic table contains 118 elements. Four of them were just added in 2016: Nihonium (113), Moscovium (115), Tennessine (117 ...

That’s worthy but flawed. Unfortunately, Abubakr’s arrangement means that the table can only be read by rotating it. That’s tricky with a textbook and impossible with most computer screens.

The periodic table brought solidity to a field of inquiry that had long been squishy. Sir Isaac Newton, in Query 31, a section in his 1717 work “Opticks,” listed and ranked chemical compounds ...

Of course, that hasn’t stopped the table from being reimagined many times. Most recently, designer Alison Haigh created this minimalist periodic table, built less for understanding the nature of ...

When IUPAC proposed modifying the periodic table’s column numbering in 1985, it took about five years to decide and another 10 to 15 years for chemists to adopt the changes, Reedijk says.
