Helium is primarily used for its inert properties, making it ideal for applications like cooling superconducting magnets in medical MRI machines and as a lifting gas in balloons and airships due to its low density. Its second main function is in shielding gas for welding, as it prevents contamination and oxidation of the weld area.

What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
What is another name for beta particle?
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.
What are Helium-4 and helium-3?
Helium is an element with the atomic number two. It has two protons in its nucleus (which is why its atomic number is two), and it comes in two stable isotopes. The most abundant one, helium-4, has two neutrons, and helium-3, which has one neutron, is found as only about one atom in a million.The element helium is an inert or noble gas, and is found on the periodic table with the other inert gases in Group 18. They're the elements down the far right column of the table. Helium, which is the second most abundant element in the universe (behind hydrogen) is about a quarter of all matter. It is a gas here on earth, and can only be liquefied if it is cooled to near absolute zero. It will not solidify, by the way. Outside earth, it is mostly found in stars where it is a plasma.We know that helium, which is colorless, odorless and tasteless, does not want to chemically combine with any other atoms. It has a valence of zero, and it is found on earth as a monatomic gas, hanging around as single atoms. It has a very low density, and this makes it good to fill balloons that are lighter than air.

Which element is abundant on the lunar surface and holds the potential to put an end to the energy crisis on earth 1. helium 1 2. helium 2 3. helium 3 4. helium 4?
Helium-3 (option 3) is abundant on the lunar surface and holds potential for use in fusion power, which could help provide a clean and sustainable solution to the energy crisis on Earth.
What are the 2 main elements that make up the sun?
Hydrogen and helium.
What are the two main elements found in the stars?
Hydrogen and helium
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
What are the 2 main functions of the reproductive system?
The two main functions of the male reproductive system are; 1 to attract and pleasure both partners to facilitate pair bonding and an opportunity to- 2 mate and fertilize an egg
How many protons and electrons does the element Helium have?
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
How are hydrogen nuclei different from helium nuclei?
The main difference is that hydrogen nuclei have 1 proton whereas helium nuclei have 2 protons. The number of neutrons depends on the "isotope". Usually, a hydrogen nucleus does not have neutrons and is simply a proton. The helium nucleus usually has 2 neutrons.
What is the atomic number for helium?
The atomic number of Helium is 2.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)

What is the simble for helium?
The symbol of Helium is He. Helium's atomic number is 2.
What are the two main gases in the Sun?
Hydrogen and Helium . When all the hydrogen is used up , it is thought that the helium will convert into carbon, and the Sun will become a Red Giant. At this late stage it will swallow up all the inner rocky planets including Earth; but that is millions of years into the future.
