HYDROGEN Meaning and
Definition
-
Hydrogen is a chemical element denoted by the symbol H and the atomic number 1. It is the lightest and most abundant element in the universe, constituting approximately 75% of its elemental mass. Hydrogen exists as a colorless, odorless, and tasteless gas in its standard state, and it is classified as a nonmetal on the periodic table of elements.
With only one electron and one proton, hydrogen has an atomic mass of approximately 1 atomic mass unit (amu). It is considered the building block of the universe due to its vital role in the formation of stars and its presence in virtually all organic compounds. Additionally, hydrogen is crucial for generating energy as it is utilized in fuel cells, where it reacts with oxygen to produce electricity and water vapor as a byproduct.
Hydrogen can exist in three isotopic forms: protium (the most abundant and stable form), deuterium (consisting of a neutron in addition to its one proton), and tritium (which contains two neutrons). These isotopes have important applications in various scientific fields, including nuclear research and medical imaging.
Hydrogen is highly flammable, making it a valuable component of rocket fuel. It is also extensively used in the petroleum and chemical industries as a reactant for the synthesis of various products, such as ammonia and methanol. A significant potential application of hydrogen lies in its potential to be a clean and sustainable energy source, as it can be produced from renewable sources and has zero greenhouse gas emissions when used as a fuel.
-
An odorless, colorless, tasteless element, gaseous at ordinary temperatures and pressure; symbol H, atomic weight 1. It is the lightest known substance, and the weight of one of its atoms is the unit of atomic weights. It is readily replaceable in many compounds by other elements or radicals, and this substitution of the hydrogen atoms in an acid forms a salt.

Etymology of HYDROGEN
The word "hydrogen" comes from the Greek words "hydor", meaning water, and "genes", meaning creator or producer. Combined, they form "hydrogen", which translates to "water-forming" or "water producer". This name was given to the element due to its role in the formation of water when combined with oxygen.
