Uses Of Helium And Atomic Properties With Characteristics

We elaborate the uses of Helium and atomic properties with characteristics. Helium is a colorless-looking chemical element with atomic number 2. Its symbol is He and it belongs to the group of noble gases and its usual state in nature is gaseous. Helium is located at position 2 on the periodic table.

On this page you can discover the chemical properties of helium and information about helium and other elements on the periodic table such as neon, hydrogen, boron or carbon. You will also learn what helium is for and know what its uses are through its properties associated with helium such as its atomic number or the usual state in which helium can be found.

You will see qualities of helium such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in helium atoms and other properties.

For some elements, some of this information is unknown. In these cases we show the properties attributed to them.

Helium properties

Noble gases like helium have little tendency to participate in chemical reactions. Helium, like other noble gases, has the following properties: It is colorless, odorless and shows very low chemical reactivity under normal conditions.

The state of helium in its natural form is gaseous. Helium is a colorless chemical element and belongs to the group of noble gases. The atomic number of helium is 2. The chemical symbol for helium is He. The melting point of helium is 0.95 degrees Kelvin or -271.2 degrees Celsius or degrees Celsius. The boiling point of helium is 4.22 degrees Kelvin or -267.93 degrees Celsius or degrees Celsius.

Uses of helium

Helium is a noble gas with the chemical symbol He. If you’ve ever wondered what helium is for , here is a list of its possible uses:

• Helium is used to cool superconducting magnets in scanners used to make MRIs.
• Since helium is lighter than air, it is used to fill airships and hot air balloons.
• Helium is used to condense hydrogen and oxygen to produce rocket fuel.
• Helium can be added to divers’ oxygen tanks so they can breathe easier. This is especially important for people who dive at great depths (more than 140 meters below sea level).
• It is used in helium-neon lasers. These lasers are used to read barcodes.
• Helium can be used to detect leaks in high pressure and vacuum equipment.
• For easily air-contaminated materials, helium is used as a shielding gas in the arc welding process.
• Helium is used as a shielding gas for the creation of silicon and germanium crystals and for the production of titanium and zirconium . It is an exceptional protective gas, since it is inert (non-reactive).
• The age of the rocks containing uranium and thorium can be estimated using helium.
• Helium is often used as a carrier gas in gas chromatography.
• Helium can be used to detect leaks (small fractures) in some vessels.

Atomic properties of helium

The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find helium within the periodic table of the elements, helium is in group 18 and period 1. Helium has an atomic mass of 4.0026 u.

Helium’s electronic configuration is 1ss. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The atomic radius or Bohr radius of helium is 31 pm, its covalent radius is 32 pm, and its Van der Waals radius is 140 pm. Helium has a total of 2 electrons whose distribution is as follows: In the first layer it has 2 electrons.
