What elements are related to 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 elements are in the same family as helium?
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 element will behave most similarly to helium?
Hydrogen is the odd one out in the periodic table. It is a gas – the same as helium – but can act in a similar way to the alkali metals.
What are two elements that have similar properties to helium?
Helium, neon, and xenon are in the same group, which are the noble gases (group 18/VIIIA). All of the atoms of the noble gases have filled valence shells–two valence electrons for helium, and eight valence electrons for the rest.
How many elements are there in helium?

What is common among helium neon and argon?
The correct answer is The outermost shells of both are fully filled. The filled outer shells of Group VIIA of the noble gases make all members of this family ( including Helium, Neon, and Argon) the most stable of all the elements. These three elements have this property in common, a filled stable outer electron shell.
What is common among helium, neon and argon?
Is helium and hydrogen similar?
Similarities Between Helium and Hydrogen Both have only 1s orbital. Both are small and light substances. Both elements belong to the s block of the periodic table. Both are nonmetals.
Which elements are in the same group?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
