-Hydrogen is a naturally occurring gas the lightest gas. chemical symbol H and atomic number 1.
-Helium is a chemical element (part of a group of chemical elements called noble gases) with the symbol He and is gas, the second most common element in the Universe (after hydrogen).
-Lithium is a chemical element (symbol Li and atomic number 3) belonging to the alkali metal
-Beryllium (Element Symbol is Be) is found in nature in various mineral compounds, not in the elemental form as they are so reactive. Atomic Number of Beryllum is 4. classified as an Alkaline Earth Metals.

The five elements discovered between hydrogen and iron since Newlands' time are helium, lithium, beryllium, boron, and carbon.
When hydrogen, lithium, and beryllium atoms combine, they form a molecule with the chemical formula LiHBe. This molecule would have a unique set of properties based on the different characteristics of each element.
When the nuclei of hydrogen and lithium are fused together, helium is produced.
Hydrogen, Helium, Lithium, Beryllium and Boron.

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.
Helium has the highest binding energy per nucleon among Hydrogen, Lithium, Helium, and Beryllium atomic elements. This is due to helium having a more stable nucleus because of its higher number of protons and neutrons, leading to stronger binding forces.
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.
