hydrogen and helium are the special elements because the electron in the outer most shell of the hydrogen is 1 but it is not a metal it is a non metal whereas in helium the electron in the outer most shell are 2 but it is not a metal there fore it is a noble gas.
No. Helium is an element, which makes it a pure substance.
No, the first element on the Periodic Table is Hydrogen, but because of its unusual behaviour it is usually placed by itself, not next to any other elements. The second element is Helium.
Helium is a nonreactive element that was discovered as a pure element. It is a noble gas with a full outer electron shell, making it stable and unreactive with other elements.
Helium is chemically inert; it does not combine with any other element.
Helium (and any other noble gas really)
Every element is unique. So, the element Helium isn't the same as any other element(s). It is however similar to other elements in it's family (inert gases).
Helium is one element and does not chemically react.
No. helium is chemically inert and does not combine with other elements.
NO!!!! He (Helium) is monatomic gas, that is it exists as single atoms, and does NOT combine with any other substance to form a compound. 'He' is the most inert element of all. It alsao has the lowest condensing point 4K4 (-269 oC) and freezing point at 2K (-271oC).
Helium is itself a chemical element and therefore is not found in any other chemical element.
Helium is chemically inert; it does not combine with any other element.
No. Helium is an element, which makes it a pure substance.
Every atom of one element has different no. of electrons than any atom of any other element.
Helium will not react with any other element.
In elements there are minerals, statics and other things every element is different!!
