What were the first elements that were found 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.
Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
Is hydrogen peroxide on the periodic table?
