noble gas
A noble gas.
Helium is a nonreactive element called a noble gas.
The element with the densest noble gas is radon (Rn). It is a radioactive noble gas that is heavier than the other noble gases, making it the densest.
The tenth element is the noble gas Neon. It is represented by the chemical formula Ne.
The element nitrogen is closest to the noble gas neon on the periodic table.
Helium is classified as a non-metallic element. It is a gas at room temperature and belongs to group 0 which is called the noble gases. It is very a very stable element and has a low density.
noble gas - hence element
Ni, Nickel is NOT a representative element.
no boron is not a noble gas but it is a nonmetal
Magnesium element has no relation with noble gas. But Mg2+ ions and noble gas neon are isoelectronic.
no. chlorine is a halogen (a group 17 element) and not a noble gas (a group 18 element). However chloride ion will have the same electronic configuration as the noble gas, argon
