The elements of the periodic table sorted by atomic number. click on any elements name for further chemical properties, environmental data or health effects. This list contains the 118 elements of chemistry. For chemistry students and teachers: The tabular chart on the right is arranged by Atomic number.

How many new periodic table are there?

four new elements
In 2016, four new elements were added to the periodic table. That means the seventh period of the periodic table is complete. Those four elements are numbered 113, 115, 117 and 118. The research groups that discovered them were from Japan, Russia, and the United States.

What are the 5 different periodic tables?

Shapes of the periodic table

• The Spiral Periodic Table (1960)
• The Curled-Ribbon Periodic Table (1975)
• The Adomah Periodic Table (2006)
• The Periodic Table of Element Scarcity (2018)
• The Periodic Table of Chemical Bonds (2019)

How are the two periodic tables different?

The main difference between Mendeleev and Modern Periodic Table is that Mendeleev’s periodic table orders the elements based on their atomic mass whereas Modern periodic table orders the elements based on their atomic number.

Is element 121 possible?

Unbiunium, also known as eka-actinium or simply element 121, is the hypothetical chemical element with symbol Ubu and atomic number 121. Unbiunium has not yet been synthesized. It is expected to be one of the last few reachable elements with current technology; the limit could be anywhere between element 120 and 124.

How are elements listed on the periodic table?

Every known element has a name and a number, which are listed in the periodic table. The periodic table outlines each element’s electron configuration, the atomic number of the element, and the chemical properties of the element.

How has the periodic table changed in the last 150 years?

The year 2019 marked the 150th year since the table was established. As the chemical properties of known elements continue to change, new discoveries of elements continue to occur. Most of the periodic table changes will result from human-made elements made by scientists using high energy accelerators.

What does atomic number mean on the periodic table?

The atomic number refers to the number of protons found in the atom of an element. Elements can be categorized into three major groups that include metals, nonmetals, and metalloids. The elements found on the left side of the periodic table are typically metals.

Who discovered the periodic table of elements?

In 1869, a Siberian called Dmitri Mendeleev presented a brand new version of the periodic table of elements to his peers at the Russian Chemical Society. He had tabulated the elements in order of their atomic weight, forming the basis for a fascinating chart that revealed patterns amongst the primary building blocks of matter.
