They are not really simlar: The hydrogen atom consists of a single proton in its nucleus. If you add 1 neutron you have the isotope Deuterium add a second neutron and you have Tritium. Although the mass increases the chemistry of hydrogen and its isotopes does not. Hellium is a different atom altogether with 2 protons in the nucleus along with 2 neutrons and its own unique chemistry. Barry

How many hydrogen atoms that fuse to form a helium is?
two hydrogen atoms
Are hydrogen or oxygen atoms used to produce helium atoms with larger masses in nuclear fusion?
Hydrogen.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
the number of helium and hydrogen atoms is the same
What heavier element is created when hydrogen atoms fuse together in the suns core?
Normal "main sequence" stars fuse hydrogen into helium during most of the star's life. The core of a star gets so hot that the hydrogen atoms begin to fuse together. As hydrogen only has 1 proton when if fuses with another hydrogen atom it has 2 protons so has become helium.
What combines to form helium atoms in a star?
Helium atoms in a star are formed through the process of nuclear fusion. In the core of a star, hydrogen atoms combine through a series of fusion reactions to form helium atoms. This happens when hydrogen atoms collide and fuse together, releasing energy in the process.
What atoms do the sun produce by fusing hydrogen atoms?
The sun produces energy by fusing hydrogen atoms into helium atoms. This is a nuclear fusion that occurs at the sun's core.
The sun fuses hydrogen atoms into what?
Hydrogen atoms fuse into helium.
Is the ratio of the amount of hydrogen and helium in the sun increasing or decreasing?
Since hydrogen atoms in the sun are fused into helium atoms, the amount of helium is increasing and the amount of hydrogen is decreasing.
How many hydrogen atoms that fuse to form a helium is?
two hydrogen atoms
Do Hydrogen and helium atoms make up fifty percent of atoms in outer space?
Hydrogen and helium make about 98% of the atoms in the solar system !
In stars energy is produced as primarily hydrogen atoms are combined to form?
helium atoms
What gas is the sun burning?
The SUN does NOT BURN gas. It is a FUSION of hydrogen atoms into helium atoms.
Stars produce energy by fusing hydrogen into?
Helium atoms
Which has the least number of atoms 5g of hydrogen or 10g of helium?
helium
Where did helium origianate from?
Helium originated from suns, where the fusion of hydrogen atoms forms the helium.
What do helium and hydrogen compose?
they compose by there atoms
Hydrogen atoms fuse and become what?
Helium
