What is the family of helium?
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
What are 5 characteristics of helium?
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can explioit these properties. Helium was the first gas used for filling balloons and dirigibles.
What is the family number for helium?
Helium is a member of the noble gas family. The noble gases are the elements in Group 18 (VIIIA) of the periodic table.
Why is helium in the noble gas family?
Explanation: Elements in this family have filled outer electron shells. Because their valance electrons are all paired there is little bonding of these electrons. This makes Helium part of the Noble gases as it inert and has a filled outer electron shell.
What element family is potassium in?
Group 1A — The Alkali Metals. Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is Lithium’s family?
The alkali metals are also called the lithium family, after its leading element. Like the other alkali metals (which are sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr)), lithium has a single valence electron that is easily given up to form a cation.
What are the properties of liquid helium?
|Properties of liquid helium||Helium-4||Helium-3|
|Boiling point at one atmosphere||4.2 K (−268.95 °C)||3.2 K (−269.95 °C)|
|Minimum melting pressure||25 bar (360 psi)||29 bar (420 psi) at 0.3 K (−272.850 °C)|
|Superfluid transition temperature at saturated vapor pressure||2.17 K (−270.98 °C)||1 mK in the absence of a magnetic field|
What is the texture of helium?
Characteristics: Helium is a light, odorless, colorless, inert, monatomic gas. Helium has the lowest melting point of any element and its boiling point is close to absolute zero. Unlike any other element, helium does not solidify but remains a liquid down to absolute zero (0 K) under ordinary pressures.
What is fluorine family?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the noble gas family?
noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
What are 5 interesting facts about helium?
Ten Facts about Helium
- Helium is the second most abundant element in the universe, and the second lightest element.
- It is estimated that our sun produces 700 million tons of helium per second.
- Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero.
What is the family name of sodium?
sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table.
What does family do my element helium belong to?
The highlighted elements of this periodic table belong to the noble gas element family. Todd Helmenstine. The noble gases are a family of nonreactive nonmetals. Examples include helium and argon. Group 18 or VIIIA; Noble Gases or Inert Gases; 8 valence electrons; Typically exist as monatomic gases, although these elements do (rarely) form compounds
What family does the element helium belong to?
The element helium belongs to to family of noble gas!!!!!
What family does helium belong too?
Helium is a member of the noble gas family. The noble gases are the elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how the elements are related to one another.
What makes helium an element?
Helium could be considered an element because there is no chemical or nuclear bonds between any of the atoms. Their outermost electron shells are full, with the first level only being able to hold two electrons. And helium, atomic number 2, only has 2 electrons. This causes the atom to be very stable and it is the reason helium is a noble gas.
