The Fifth Amendment to the U.S. Constitution provides that no person shall âbe subject for the same offence to be twice put in jeopardy of life or limb.â Itâs a relatively straightforward concept: The government canât prosecute someone more than once for the same crime.
Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.Examples of elements include iron, copper, hydrogen and oxygen.eaning. A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Distinguishing Feature. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.
An element is a substance consisting of atoms which all have the same number of protons-i.e. the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods. Although an element's atoms must all have the same number of protons, they can have different numbers of neutrons and hence different masses.
