What is a nucleosynthesis mean?
Nucleosynthesis is the process of creating new atomic nuclei from preexisting nucleons (protons and neutrons).
The subsequent nucleosynthesis of the elements (including all carbon, all oxygen, etc.) …
occurs primarily in stars either by nuclear fusion or nuclear fission..
What do you call a star that died?
While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called a supernova. The death of massive stars can trigger the birth of other stars.
Which is the lightest gas in the world?
HydrogenHydrogen is the lightest, most abundant and explosive gas on Earth. The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas. It is 220 times heavier than the lightest gas, Hydrogen.
What are the types of nucleosynthesis?
There also four types of Nucleosynthesis namely the Big Bang, Stellar, Explosive Nucleosynthesis, and Cosmic ay Spallation. Big Bang Nucleosynthesis is the reaction that came within three minutes from the formation of the Universe.
At what point is a star born?
At what point is a star born? When the core of a protostar has reached about 10 million K, pressure within is so great that nuclear fusion of hydrogen begins, and a star is born.
What is the name of the most beautiful star?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth’s night sky. The name means “glowing” in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star.
What is rarest element on earth?
element astatineA team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What is the lightest element on earth?
HydrogenThe lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
What is the heaviest element in the universe?
uraniumHeaviest Element in Terms of Atomic Weight Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289).
What metal is heavier than gold?

What is the heaviest metal on earth?
OsmiumOsmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
What are the heavy elements?
A heavy element is an element with an atomic number greater than 92. The first heavy element is neptunium (Np), which has an atomic number of 93. Some heavy elements are produced in reactors, and some are produced artificially in cyclotron experiments.
What is a star birth called?
Like people, stars are born, they grow old and they die. Their birth places are huge, cold clouds of gas and dust, known as ‘nebulas’. The most famous of these is the Orion nebula, which is just visible with the unaided eye.
What is the rarest element in the universe?
AstatineAstatine is the rarest naturally occurring element.
