What has an atomic number of 1 and is the lightest element on the periodic table?
Hydrogen! It's the lightest of the elements, the only element whose atoms (typically) contain no neutrons, and it's the most abundant element in the universe because it's the main ingredient in stars, which make up nearly all the universe's mass (as far as we know.)
The element has a mass number and atomic number of 1?
The element with a mass number and atomic number of 1 is hydrogen. It is the lightest and most abundant element in the universe. Hydrogen is a key component of water and plays a vital role in the formation of stars through nuclear fusion.
How is it possible to know that the element hydrogen exists throughout the universe?
Hydrogen is the most abundant element in the universe due to its simple atomic structure and presence in stars. Scientists observe hydrogen through its spectral lines in the light emitted from stars and galaxies, confirming its widespread existence. Additionally, studies of cosmic microwave background radiation and the chemical composition of various celestial bodies provide further evidence of hydrogen's presence.
What is thev connection between universestar and galaxy?
The universe comprises all matter in space. This includes a very large number (200 billion to 2 trillion) galaxies. Each galaxy comprises a very large number of stars: our contains 100 thousand million stars.
What is the difference between hydrogen and other elements?
Hydrogen is the lightest and most abundant element in the universe. It is unique in that it is the only element that does not contain any neutrons in its nucleus. This makes hydrogen an important element in chemical reactions and plays a crucial role in the formation of stars and the universe.
What element is the most abundant in the universe and all stars are made of it?
The most abundant element in the universe is hydrogen.
What are the heavier element in the universe formed by?
a series of stars
Which is the Element abundantly present in the universe especially in stars?

What are the initial starting particle for nuclear fusion in stars?
Stars are mostly hydrogen, the simplest element in the universe - also, the most common element in the universe. All the elements heavier than hydrogen were formed by nuclear fusion, where the atoms fuse together at very high temperatures and pressures. So carbon, oxygen, iron and everything else is like the "ash" from the nuclear "fire" in stars that once burned in other skies and then were destroyed in nova and supernova explosions.
What is the sun's most common type of hydrogen?
Hydrogen is the sun's most common element. Hydrogen is "H," element number 1, on the Periodic Table of elements. It is the most abundant element in the universe, because it fuels the stars.
What element has the most effect in universe?
Hydrogen - from it all other elements are made in the stars
What produces all known element in the universe other hydrogen?
fusion reactions in stars
What is the secondmost abundant element in the universe?
Helium is believed to be the second most abundant element in the universe, because the energy of most stars arises from the fusion of hydrogen to produce helium.
The total number of stars in your observable universe?
There are estimated to be around 100 billion galaxies in the observable universe, with each galaxy containing hundreds of billions of stars. This means that the total number of stars in the observable universe is in the order of 10^24 (1 septillion) stars.
Hydrogen is most common type of what in the sun?
Hydrogen is the sun's most common element. Hydrogen is "H," element number 1, on the periodic table of elements. It is the most abundant element in the universe, because it fuels the stars.
