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.

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.
