Helium is a chemical element. It is inert and a gas (at room temperature).
Helium exists in liquid form only at extremely low temperatures.
The boiling point and critical point depend on the isotope of the helium. He-4 boils at 4,2 K and He-3 boils at 3,2 K (1 atm pressure).
At normal pressures helium is never a solid. Solid helium requires a temperature of 1-1.5 K (about −272 °C or −457 °F) and about 25 bar (2.5 MPa) of pressure.

What is helium considered as?
Helium is considered as totally inert and unreactive. It is the first element of the noble gases.
What element that is considered unreactive because it has a filled outer energy level is?
noble gases helium to be exact
An element that is considered to be unreactive because it has a filled outer energy level is?
Helium
Is helium expensive?
Yes, helium is considered to be expensive. It is a finite resource and its production and supply are limited. The cost of helium has been increasing in recent years due to the growing demand and limited availability, which makes it relatively expensive compared to other gases.
What is the element name for He?
Helium Helium
What is helium considered as?
Helium is considered as totally inert and unreactive. It is the first element of the noble gases.
Is Helium considered neutral?
because it is
Is Helium considered inert?
Yes.
What element that is considered unreactive because it has a filled outer energy level is?
noble gases helium to be exact
When helium has an atomic number of two its outer energy level is full. Helium is considered?
Inert I believe
What does helium react chemically with?
Helium is considered an inert noble gas. Only some unstable compunds of helium are known today: HeNe, HgHe10, WHe2.
Does nonmetals have hydrogen and helium in it?
Both hydrogen and helium are considered as non metals, yes.
Does helium have conductive in it?
Helium in a chemical element, and an inert gas. It does not want to be an electrical conductor, so it is considered an insulator.
Is helium considered as a pure substance?
Yes, because it is an Element.
Why is helium considered a gas?
helium has completely filled valence orbitals similar to that of noble gases and is chemically inert at room temperature.
Is helium a noble gas or a metal?
Helium is an inert or noble gas, and it remains a gas at anything but the lowest temperatures. It is a member of Group 18 of the periodic table, and helium is not considered a metal.
Is helium cosidered matter?
Yes. matter is anything that occupies space and has volume. Helium gas will obey this
