What else can I help you with?
Do professional soccer balls contain helium?
No, professional soccer balls do not contain helium. They are typically made of materials like leather or synthetic materials.
What is the size of the atom in helium?
The size of an atom is typically measured in terms of its atomic radius, which for helium is approximately 31 picometers (pm), or 0.31 angstroms. This corresponds to the distance from the nucleus to the outermost electron cloud in a helium atom.
Do helium neon and argon combine with iron?
Helium and neon do not typically react with iron under normal conditions. Argon is inert and does not chemically react with iron.
What is the charge of a neutron in helium?
Neutrons have no charge, so in a helium atom, the neutron would also have no charge. Helium typically has two protons (+1 charge each) and two neutrons (no charge), resulting in a neutral overall charge.
Can you make helium using a specific process or method?
Yes, helium is typically obtained through the process of extracting it from natural gas deposits. This involves drilling wells and separating the helium from the natural gas using a series of purification steps.
Where do companies get helium from?
Companies typically source helium from natural gas deposits. Helium is extracted during the natural gas production process, as it is a byproduct of the gas that is released. Helium can also be obtained through the refining of crude helium gas.
Who produces Helium-3?
Helium-3 is not produced; it is a naturally occurring isotope formed through the decay of tritium. It can also be extracted during the operation of nuclear reactors and obtained through the decay of tritium in nuclear weapons.
What is the purpose of the helium gas in the GC machine?
The purpose of the helium gas in the GC (gas chromatography) machine is to act as the carrier gas. The helium gas carries the sample through the column, allowing for the separation and analysis of the various components in the sample. Helium is commonly used as the carrier gas due to its inertness and low molecular weight, which facilitates efficient sample transport.
How long does Helium Flash in Stars Solar Masses last?
The helium flash in stars of solar masses typically lasts only a few hours to a few days. During this short-lived event, helium is rapidly converted into carbon and oxygen in the star's core, leading to a release of a significant amount of energy.
What are common compounds for helium?
Common compounds for helium include helium-3 (He-3) and helium-4 (He-4), which are isotopes of helium. Helium is typically chemically inert and does not readily form compounds with other elements under normal conditions.
What is helium plus helium?
When two helium atoms combine, they form a molecule of helium gas (He2), which is also known as a dihelium molecule. This molecule is quite rare and unstable under normal conditions, as helium typically exists as a monoatomic gas.
The helium flash converts helium nuclei into?
The helium flash converts helium nuclei into carbon nuclei through the fusion process in the core of a star. This process occurs in stars with a mass greater than about 0.8 times the mass of the Sun during the later stages of helium burning. The intense energy released during the helium flash helps stabilize the star against gravitational collapse.
Is helium a nutrient?
No, helium is not a nutrient. Nutrients are substances that provide nourishment to organisms for growth and maintenance. Helium is a chemical element, typically a gas, and is not used by living organisms for nutrition.
Are hydrogen or oxygen atoms used to produce helium atoms with larger masses in nuclear fusion?
Hydrogen atoms are used to produce helium atoms with larger masses in nuclear fusion. During the fusion process, hydrogen isotopes (such as deuterium and tritium) combine to form helium, releasing vast amounts of energy in the process. Oxygen atoms are not typically involved in nuclear fusion reactions to produce helium.
On a cylinder of helium what colour is the label?
The label on a cylinder of helium is typically brown or green in color.
What is helium made from?
Helium is an element on the periodic table and is one of the basic building blocks of the universe. It is formed through nuclear fusion in stars, releasing helium during the process. On Earth, helium is extracted from natural gas deposits through a process called fractional distillation.
How discovered helium?
Pierre Janssen, who was a French astronomer discovered helium in 1868. It was the English astronomer Norman Lockyer who proposed the name helium after the Greek name of the sun, Helios.
