The total number of elements present in the modern periodic table is 118. The number of non-metals is 18. The number of metalloids
Metalloid
A metalloid is a chemical element with properties in between, or that are a mixture of, those of metals and nonmetals. There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the literature of chemistry.
Bromine
Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodin…
How many elements are in the periodic table?
The periodic table. There are 118 elements on periodic table. The number of protons in an element gives the atomic number of the element. In 2016 four more elements were added into the periodic table. An element refers to a substance made of atoms of the same kind.
What information is provided by 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. 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.
How many new elements have been discovered in the periodic table?
Six new elements were discovered between 2012 and 2016, filling the gaps that were remaining at the bottom of the periodic table. 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.
What is the most recent version of the periodic table?
The online version of the Periodic Table has been updated to the most recent printed version, which is dated September 2010. There was also a September 2009 version. Since version 4, elements have been added such that there are no "missing elements" from 1 to 118. Several official names have been added for high Z elements.
