What do stars lose when they lose their outer layer?
When stars lose their outer layers, they primarily expel gas and dust, which can include hydrogen, helium, and heavier elements. This process often occurs during the later stages of a star's life, such as during a red giant phase or in supernova explosions. The ejected material contributes to the interstellar medium, enriching it with elements essential for the formation of new stars and planets. Additionally, the star may lose significant mass, affecting its gravitational pull and evolutionary path.
Why the outer planets did not lose the lighter gases in their atmospheres?
The outer planets, such as Jupiter and Saturn, have strong gravitational fields that are capable of retaining lighter gases like hydrogen and helium. Their significant mass allows them to hold onto these gases despite their higher thermal velocities. Additionally, the colder temperatures in the outer solar system help reduce the kinetic energy of gas molecules, making it less likely for them to escape into space. Consequently, these planets have retained their thick atmospheres composed primarily of lighter gases.
What rule are hydrogen and helium excepted from?
The elements hydrogen and helium are exempted from the octet rule. The octet rule, as you might recall, states that elements prefer to have eight electrons in their valence shells. Hydrogen has a lone electron in its valence shell, and cannot begin to "borrow" electrons to create a shell with eight electrons in it. Remember that its electron, a 1s1 electron, is in the 1s shell. Helium has a full 1s shell with its two electrons (1s1, 1s2). It has no interest in any other electron configuration because its valence shell is full. The first two elements on the periodic table are the exceptions to the octet rule. A link can be found below.
What separates the terrestrial and jovian planets?
In our solar system, the asteroid belt lies between the two types of planets. Whether this is due to some overarching influence or merely coincidental cannot be determined at the present time. Mercury, Venus, Earth, and Mars are small rocky, terrestrial planets. Jupiter, Saturn, Uranus, and Neptune are larger, predominantly gaseous planets. Beyond Neptune are many small plutoids and other icy bodies, some of which approach the size of the terrestrial planets. Their gaseous composition, however, means that they would lose much of their mass if they were closer to the Sun.
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
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.

Consequently, these planets have retained their thick atmospheres composed primarily of lighter gases.
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?
During the creation of the planets, gravitational forces pulled the heavier planets towards the center. The lighter gas filled planets by default established further orbits. It is thought that heat caused the inner planets to lose their gas composition.
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.
