Elements and compounds (pure substances) cannot be broken down by physical changes.
Sodium and francium are elements. Elements are substances that cannot be broken down into simpler substances by chemical means, whereas compounds are substances composed of two or more elements chemically bonded together.
Element Compounds can be broken down to elements (atoms) which cannot be decomposed further into simpler substances (that's why they're called a-toms, from Greek 'à-tomos', meaning 'un-sliceable'.
Elements can not be made into simpler substances even by chemical reactions. Compounds can be broken down to simpler substances and eventually to elements. One useful observation is that an element will burn to give only one product, whereas a compound will give more than one.
The only possibility is to produce its two constituent elements.
Elements are substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms bonded together. Elements cannot be broken down into simpler substances, while compounds can be broken down into their constituent elements through chemical reactions.
Elements
Compounds are made up of 2 or more elements.Compounds can be broken down into simpler substances by chemical means, but elements cannot.Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
Compounds are made of two or more substances joined together, and elements are a pure substance that can't be broken down into simpler substances.
Elements and compounds are called substance....subtances can be either elements or compound....an elementis a substance that cannot be separated into simpler substances by ordinary means...!!a compound is a pure substance that contains two or more elements combined in afixed proportion.......example of the formation of a comp. :1. Sodium plus chlorine --> sodium chloride
Elements are made up of only one thing. While a compound is made of two of more elements. Here is an example. H2O. Water is hydrogen and oxygen.

There are more non-elements than elements. Elements are substances that cannot be broken down into simpler substances by chemical means, while non-elements can encompass a wide range of substances such as compounds, mixtures, and other forms of matter that are not elements.
