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.
False.
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
The first elements discovered and placed on the periodic table were hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, and magnesium. These elements were identified based on their unique chemical properties and atomic structures.
hydrogen (and helium)
False.
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.
False (Hydrogen has the first position, Helium is the most stable)
Hydrogen is the first and helium is the second.
Period 1 refers to the top row of the periodic table. These elements are Hydrogen and Helium.
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
The first period in which you'll find 18 elementSis the fourth (4th) period: going from 19-K (potassium) to 36-Kr (Krypton).Maybe this is the answer to the question you didn't ask but probably meant to ask.(It is impossible for one element to contain 18 elements, you see!)The element with 18 electrons in the 3rd period (= row) of the periodic table is ArgonIn the first period of the periodic table there are only two elements: H (1 eln.) and He (2 eln's) and have nothing to do with the number 18.
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

No. It is hydrogen. Refer to the related link.
