Where are the most active elements located on periodic table called?
The most reactive elements on the periodic table are the alkali metals and the halogens, and are located in the very left row and second row from the right respectively
Who was the natural philosopher who published the very first Periodic Table of Elements?
Russian chemist Dmitri Mendeleev (1834-1907) published the first periodic table of elements in 1869.
Where are hydrogen found on the periodic table?
Hydrogen is found at the very top left of the periodic table. It is the first element on the periodic table and it is shown with the atomic symbol H.
How can you identify the elements in a family on the periodic table?
every column on the table represents a family that react similarly with other elements.
Define group as it relates to the periodic table?
A group is a vertical column on the periodic table. The elements in a group have very similar chemical properties because their outer electron configuration is the same. Ex: the first column on the left, Li, Na, K etc. Each of these has one outer electron, causing each to react in very similar ways. They lose that electron and form a positive ion.
Elements on very first Periodic Table?
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Where are the most active elements located on periodic table called?
The most reactive elements on the periodic table are the alkali metals and the halogens, and are located in the very left row and second row from the right respectively
What are the elements on the right side of the periodic table called?
Noble gases: helium, neon, argon, krypton, xenon, radon, ununoctium.
Where are metals and nonmetals are located on the periodic table?
Non-metals are located on the very right of the Periodic Table. Metals are on the left.
What is the similarities in the modern periodic table and Mendeleev's table?
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
What are the next elements after the sixth one?
There are far to many elements following the 6th on in the Periodic Table. Included below is a link to a very nice Periodic table.
What does it mean when elements are on the right of the periodic table of elements?
The Elements on the far right side of the Periodic Table of the Elements are known as the Nobel Gasses.
Who was the natural philosopher who published the very first Periodic Table of Elements?
Russian chemist Dmitri Mendeleev (1834-1907) published the first periodic table of elements in 1869.
The elements with the smallest atomic radii are found in the?
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
Where are hydrogen found on the periodic table?
Hydrogen is found at the very top left of the periodic table. It is the first element on the periodic table and it is shown with the atomic symbol H.
How different are elements on the periodic table?
Very different. Each element is unique.
Which family is very stable and nonreactive?
Elements in group 18 of the periodic table.
