  • Alkali metals.
  • Alkaline earth metals.
  • Rare earth metals.
  • Crystallogens.
  • Pnictogens.
  • Chalcogens.
  • Halogens.
  • Noble gases.

What was added to the periodic table in 2009?

Its so-called atomic number 112, hence the provisional name “element 112”, is the sum of the atomic numbers of the two initial elements: zinc has the atomic number 30 and lead the atomic number 82.

How many groups are in the periodic table 2021?

There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.

Why is there no element 119?

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.

What is Group 7 called in the periodic table?

How many elements have been discovered since 2000?

5 elements
The discovery of the elements: from Antiquity to Middle Ages (13 elements), Middle Ages to 1799 (21 elements), 1800 to 1849 (24 elements), 1850 to 1899 (26 elements), 1900 to 1949 (13 elements), 1950 to 1999 (16 elements) and since 2000 (5 elements so far).

Are there 8 or 18 groups in the periodic table?

There is eighteen groups on the periodic table in total, and each periodic table group contains elements with the same number of valence electrons. The number of valence electrons present dictates the properties of an element.

What are the 18 groups in periodic table?

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.

Is Ununennium possible?

Given the structure of the periodic table, the existence of ununennium can be fairly confidently predicted, and some scientists have also made speculations about the element’s potential chemical properties. Given its position on the periodic table, ununennium is probably going to be an alkaline earth metal.
