Saturn
Good question. Jupiter is primarily made of elements that we consider gasses, like Hydrogen and Helium. However, the pressures deep within Jupiter's core are likely to have compressed it into something we cannot duplicate on Earth; liquid metallic hydrogen. We're not certain of this, of course, because we can only see the outer layers.
H- Comment: I haven't checked this, but I think "neutral hydrogen atoms" is a more likely answer.
All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.

In our solar system both the gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune (sometimes also called gas giants) are believed to have rocky cores, likely composed of silicates, ice, and possibly heavier elements like metals such as nickel/iron although their true composition is not well known. Above that are deep layers of metallic hydrogen. Their atmospheres are predominatly molecular hydrogen and some helium, with other compounds such as ammonia present in small amounts on Saturn. The ice giants Uranus and Neptune are so named for having much more icy compounds such as water, ammonia, and methane, and some nitrogen and hydrocarbons. The presence of methane in outer layers is thought to give Neptune its blue color.
Saturn, Jupiter and other gas giants most likely contain liquid and metallic hydrogen
No. Liquid metallic hydrogen only forms when hydrogen is subjected to extreme pressure. Hydrogen is present in trace amounts in Earth's atmosphere in gas form, under low pressure. The core is composed primarily of iron. Liquid metallic hydrogen likely exists in the gas giants Jupiter and Saturn.
If your cellphone is magnetic, the reasons are most likely the facts that magnetic materials, such as iron, nickel, or cobalt, are used in the manufacture of some of its parts, and that there are electric currents flowing in some places inside it.
Jupiter, being a gas giant, lacks any landmasses. It is a gaseous ball of mostly hydrogen and helium, with trace amounts of hydrocarbons and other heavier elements and compounds. Most likely the center of Jupiter is a core of metallic hydrogen: hydrogen compressed so much that it has taken on similar properties of metal. This is similar to the liquid iron and nickel core as the Earth; both planets have magnetic fields, but Jupiter's is many times more powerful.
A metallic taste in your mouth will very likely come and go. The metallic taste most likely comes from blood in the mouth and will heal quickly.
Depends on the hydrogen gradient. If hydrogen is still flowing down it's concentration gradient through the ATP synthase then some ATP will be made, at least until equilibrium is reached.
Canyons are formed by flowing water.
Elements in the d-block usually form metallic bonds with high strength.
No. They will most likely form an ionic bond. Metallic bonds form between the atoms of a metal, such as gold or iron.
the amount of energy the flowing H+ ions have
Iron is the most metallic in nature among these three. Therefore, it has the most strongest metallic bonds
Hydrogen and hydrogen+fluorine.
