As the atomic number differs from every element and so that atomic mass also differs. There are a total of 118 elements that have been identified, divided between metal, metalloids and non-metals. Atomic elements are the most stable chemical elements; mainly the noble gases. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Summary – Element vs Molecule. To exist they join together to form molecules, O2 where sharing electrons gives them stability. 5. Start studying atomic elements, molecular element, molecular compound, or ionic compound. Elements and compounds are pure chemical substances found in nature. Ionic Bonds. Some chemical elements are highly radioactive since they are highly unstable. Elements with similar chemical properties are called groups. Element vs. Another thing needs to be mentioned here is about isotopes and allotropes. Atoms can join with other atoms in various ways, and form thousands of molecules and other compounds. If my molecule has more than one flavor of ice cream, I can call it a compound. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. Diatomic compounds consist of two different elements. Elements in the same group or periods share certain common characteristics, and some properties may change sequentially when you go through a group or period. Each element has its own set of properties. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Main Difference – Atomic Number vs Atomic Weight. Fe (iron) is an element that is represented with no subscript, so it is an atomic element. Some elements such as oxygen do not exist as atoms (do not have a stable octet).
