Radium react with halogens (F, Cl, Br, I), N, water, etc.
Yes, radium is a reactive chemical element.
why helium does not react with other elements to form compounds
The Noble gasses.
because not all elements and compounds react with each other
There are very many elements which will do that.
Radium react with halogens (F, Cl, Br, I), oxygen, nitrogen, water, etc.
why helium does not react with other elements to form compounds
Nonmetals may react with metal to form ionic compounds (salts) or other nonmetal elements to form organic compounds.
The Noble gasses.
because not all elements and compounds react with each other
because not all elements and compounds react with each other
because not all elements and compounds react with each other
Elements or compounds which cannot react with each other.
There are very many elements which will do that.
Mercury forms amalgams with most metals. It can react with non-metals to form to types of compounds: mercurous and mercuric compounds.
Radium react with halogens (F, Cl, Br, I), oxygen, nitrogen, water, etc.
Correct Helium can form unstable compounds (excimers).
Yes, all elements have chemical properties related to their ability to react with other elements or compounds.
