Helium has 2 valence electrons and it should theoretically be placed along with group 2 elements.
But since helium has completely filled orbitals (as do the noble gases), it is placed along with the noble gases.
helium is in the family of noble gases according to the periodic table
what is lead's position on the periodic table, and it's chemical properties based on that position
The position of hydrogen is not well-defined in the periodic table because it exhibits properties of both alkali metals and halogens. This makes it challenging to categorize hydrogen into a specific group based on its properties alone. Additionally, hydrogen's electronic configuration and chemical behavior do not fit neatly into any one group, further complicating its placement in the periodic table.
Bromine is on 35th position in the periodic table.It has 35 atomic number.It is a halogen.
At present, the element has been labeled as ununpentium, which refers to its position in the periodic table- 115th.
Please be more clear: the position of fluorine in the periodic table is justified - it is a halogen, group 17, period 2.
helium is in the family of noble gases according to the periodic table
It is not an exception: it is at the top of group 18, the noble gases which is exactly where it should be.
Position of Periodic Table describes chemical properties. it is estimated from its position in table.

Diamond is not listed on the periodic table as it is a form of carbon, which is located in Group 14 of the periodic table.
Periodic Table is expressed as rows and columns. It is used by locating the position of element.
