What rule are hydrogen and helium excepted from?
Hydrogen and helium are exceptions to the octet rule in chemical bonding. Hydrogen can either gain one electron to achieve a duet configuration or lose one electron to be left with a single electron. Helium is already stable with two electrons in its outer shell.
What separates the terrestrial and jovian planets?
The terrestrial planets are closer to the sun, smaller in size, and have solid surfaces made of rock and metal. Jovian planets are further from the sun, larger in size, and primarily composed of hydrogen and helium gas with no solid surfaces.
What element that has 1 electron?
Hydrogen has 1 electron in its outer shell. other elemnts also have just one electron in their outer shell, the alkali metals, group1; lithium, sodium potassium, rubidium, caesium, frankium the coinage metals, group 11; copper, silver, gold
Why do different planets have different atmospheres?
Different planets have different atmospheres due to variations in their composition and distance from the sun. Factors like the planet's size, gravity, and proximity to the sun determine what gases are retained in the atmosphere, leading to unique compositions. Active processes like volcanic activity and biological activity can also contribute to the diversity of atmospheric compositions across planets.
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
What did the planets near the sun lose because of the sun's temperature?
Planets near the sun likely lost lighter elements like hydrogen and helium due to the sun's high temperature and solar wind. These elements were blown away, leaving behind the heavier elements that make up the terrestrial planets closer to the sun.
How many electrons does it take for hydrogen and helium to become stable?
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
What element has 1 protons 1 neutrons and 2 electrons?
It is hydrogen element. It is tritium isotope of hydrogen.
What will happen if Jupiter dies?
Jupiter is a gas giant and does not "die" in the traditional sense. It is made up primarily of hydrogen and helium, similar to a star. If Jupiter were to somehow lose its gas and dissipate, it would not have a direct impact on our solar system, since it does not support life as we know it.
What element has two electrons?
The only neutral atom with two electrons is helium; however, lithium will lose one electron when becoming an ion to have two electrons. Hydrogen can also gain an electron (compounds called hydrides) to have two electrons also.
Do acids lose or gain hydrogen ions?
Acids lose hydrogen ions when they donate them in a chemical reaction, making them stronger acids.
What is the most likely charge on an ion when hydrogen forms an ion?
When hydrogen forms an ion, it is most likely to have a charge of +1, forming a hydrogen ion (H+). This is because hydrogen has one electron in its outer shell, so it tends to lose this electron to achieve a stable electron configuration similar to that of helium.
Why are the inner planets composed of heavy elements and outer planets composed of gas?
The inner planets are closer to the sun and the heat from the sun caused the lighter elements to be blown away, leaving behind heavier elements. The outer planets are further away from the sun, so the lighter gases were able to remain and accumulate to form gas giants.
Why did early earth lose most of the hydrogen and helium that most likely made up the first atmosphere?
Early Earth likely lost most of its hydrogen and helium because they are lightweight gases that could escape the planet's gravity due to their high kinetic energy. This loss likely occurred during the early stages of Earth's formation when the planet was still molten and experiencing intense heat.

The terrestrial planets are closer to the sun, smaller in size, and have solid surfaces made of rock and metal. Jovian planets are further from the sun, larger in size, and primarily composed of hydrogen and helium gas with no solid surfaces.
Why would the sun explode?
As stars grow older, they lose energy. The sun is growing older and it is losing hydrogen and helium (the gases on the outer region). When the sun loses all of its energy it explodes. It then becomes a black dwarf.
