because its the element that created the earth
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
NO!!! Hydrogen (H) is the first element on the Periodic Table. Reason Atomic No. = 1 Atomic mass( of protium) = 1 Carbon lies 6th position. Atomic No. = 6 Atomic mass = 12
Hydrogen is located in Group 1A of the Periodic Table.
"H" stands for Hydrogen on the periodic table.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
It is placed in group 1, period 1 on the modern periodic table
The symbol for hydrogen on the periodic table is H.
No, the symbol "H" stands for Hydrogen on the periodic table. The symbol "He" stands for Helium on the periodic table.
Hydrogen is found in group 1 row 1 of the periodic table
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.
