generally chemically inert
Helium is a noble gas. It is part of the group of gases known as noble gases which have low reactivity due to their full outer electron shells.
Noble gases are known for their low reactivity because they have a full valence shell of electrons, making them stable and less likely to form compounds with other elements.
A noble gas is a nonmetal. It belongs to a group of elements that are generally inert, have low reactivity, and do not readily form compounds with other elements.
This is a noble gas (group 18).
Noble gases have a very low chemical reactivity and have copletely filled the outer shell of elctrons.

No, argon is not a metalloid. It is catagorized as a noble gas.
A noble gas is a nonmetal. It belongs to a group of elements that are generally inert, have low reactivity, and do not readily form compounds with other elements.
Argon is a colorless and odorless gas with low reactivity. Its opacity is generally very low as it is a noble gas, meaning it does not readily react with other elements in the air.
This is a noble gas (group 18).
Noble gases have a very low chemical reactivity and have copletely filled the outer shell of elctrons.
Xenon as it is a noble gas. Noble gases are inert and do not react with anything. Selenium is a solid Chlorine is a green coloured highly reactive poisonous gas. Carbon is a non-metallic solid.
No, xenon is a noble gas. It belongs to group 18 of the periodic table, known as the noble gases, which are characterized by their low reactivity and full outer electron shells.
Krypton is a noble gas, which means it is an inert element with a low reactivity. It is typically found in a gaseous state and does not have a solid form at normal temperatures.
it is colourless oderless tasteless and glows
No, helium is not ductile. Helium is a noble gas with very low reactivity and does not exhibit ductility like metals or other materials.
