The Answer:
And, the answer for the the question is :
Explanation:
Hydrogen is the element with the lowest atomic weight on the periodic table. Hydrogen is not only the most common element in the universe, but it is also the element with the simplest chemical structure. It is located at the top of the periodic table. Additionally, it is the only known element that does not have any neutrons in its atoms. Humans put hydrogen to use in a wide variety of applications, including as a fuel for rockets, a component of fertilizer, and in cleaning products. At one point, hydrogen was also used for hot air balloons, though after the Hindenburg disaster it was declared too dangerous for use due to flammability. Helium, an element with a mass that is two and a half times that of hydrogen, comes in at number two. It is common knowledge that balloons make use of this gas. The third spot is held by lithium. On the other hand, osmium is the heaviest element in the periodic table. It weighs more than 1,400 pounds per cubic foot, which makes it significantly heavier than lead. Platinum, an element that is frequently used in jewelry, comes in a close second in terms of weight.
Hydrogen is the lightest element on the periodic table, with an atomic number of 1 and an atomic weight of 1.008. It is a colorless, odorless, and highly flammable gas that is abundant in the universe and plays a critical role in many chemical processes.
Hydrogen is the most common element in the universe, making up about 75% of its elemental mass. It is found in stars, planets, and interstellar space, and is a key component in the formation of stars and galaxies.
On Earth, hydrogen is found in a variety of compounds, including water, organic compounds, and minerals. It is also used in a variety of industrial processes, including the production of ammonia, methanol, and petroleum refining.
Hydrogen is unique among the elements in that it can exist in three different isotopic forms. The most common isotope is protium, which has one proton and one electron. Deuterium and tritium are the other two isotopes, with deuterium containing one proton and one neutron, and tritium containing one proton and two neutrons. These isotopes have important applications in nuclear energy and weapons.
Hydrogen is also important in the study of physics and chemistry. Its simple atomic structure makes it a useful tool for understanding atomic and molecular interactions, and its reactivity allows it to participate in a wide range of chemical reactions.
hydrogen is the lightest element on the periodic table and is abundant in the universe. It is a key component in the formation of stars and galaxies, and plays a critical role in many industrial processes. Its unique properties make it an important tool for understanding physics and chemistry, and its isotopes have important applications in nuclear energy and weapons. Hydrogen’s importance in the universe and in scientific study make it a fascinating element to study and understand.
