is it true or false
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! :)
No, both hydrogen and sulfur are elements. One does not contain the other.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Hydrogen: represented on the table with by the symbol HIt has the lightest atomic weight of all elements at 1.00794Hydrogen is the most abundant chemical element, constituting roughly 75% of the universe's elemental mass.
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.

No, the first element on the Periodic Table is Hydrogen, but because of its unusual behaviour it is usually placed by itself, not next to any other elements. The second element is Helium.
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.
Hydrogen is the first, smallest, and lightest element. It is number 1 in the periodic table of elements.
Hydrogen is the first element on the periodic table of elements. Hydrogen is also a gas.
Hydrogen is the very first element of the periodic table.It is used in hydrogen fuel.It has atomic number 1.It is lightest element known.
The elements in the periodic table are arranged according to their atomic numbers, which are the numbers of protons in their atomic nuclei. The atomic number of hydrogen is 1 because it's atoms have one proton, which is why it's the first element in the periodic table.
No, both hydrogen and sulfur are elements. One does not contain the other.
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
