What is matter or a substance at the top split into pure substances and mixtures? Pure substances is then split into elements and compounds. Mixtures can be heterogenous or homogenous. Heterogenous mixtures can be suspensions or colloids and homogenous mixtures include solutions
The term being described here:
An element which has a different number of neutrons from the normal element. It also exhibits properties which make it unstable and requires extensive containment and protective measures.
