They are both in period 1, so have their valence electrons in the first energy level. However, helium has 2 protons in the nucleus holding on to those electrons. Hydrogen has only 1 proton holding the electrons. Thus it takes more energy to remove an electron from helium than from hydrogen.
What else can I help you with?
When does helium fusion begin in a star?
Hydrogen undergoes nuclear fusion to form helium at a temperature of 107 K
What is the temperature which fusion of hydrogen into helium begins?
Fusion of hydrogen into helium typically begins at temperatures around 10 million degrees Celsius. At this temperature, hydrogen nuclei can overcome their electrostatic repulsion and come close enough for the strong nuclear force to initiate fusion reactions.
What fusion in stars occurs to create the element helium?
Hydrogen fusion occurs in stars to create helium. This process, known as nuclear fusion, involves the fusion of hydrogen nuclei to form helium nuclei, releasing large amounts of energy in the process.
What kind of change is hydrogen to helium?
nuclear fusion of hydrogen to form helium
How is helium formed from hydrogen?
Helium is formed through nuclear fusion in stars. In the core of a star, hydrogen atoms undergo fusion to form helium. This fusion process releases energy and is the source of a star's energy.

When does hydrogen-helium fusion and helium-carbon fusion occur in stars like our sun?
When hydrogen stocks run out
What kind of change is hydrogen to helium?

How is helium formed from hydrogen?
Helium is formed through nuclear fusion in stars. In the core of a star, hydrogen atoms undergo fusion to form helium. This fusion process releases energy and is the source of a star's energy.
What conditions are present in stars that cause the hydrogen to form helium?
The extreme pressure and temperature in a star's core cause hydrogen atoms to undergo nuclear fusion, combining to form helium. This fusion process releases a great amount of energy, helping to sustain the star's luminosity.
What does nuclear fusion convert hydrogen into?
Nuclear fusion converts hydrogen atoms into helium atoms. In the fusion process, hydrogen nuclei combine to form helium nuclei, releasing a large amount of energy in the form of heat and light.
Why do hydrogen and helium make up the sun?
hydrogen & helium combine with fusion of four process
What element is transformed in solar fusion?
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.
Where did helium origianate from?
Helium originated from suns, where the fusion of hydrogen atoms forms the helium.
