The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. Atoms lack a well-defined outer boundary‚ so their dimensions are usually described in terms of an atomic radius. This is a measure of the distance out to which the electron cloud extends from the nucleus. However‚ this assumes the atom to exhibit a spherical shape‚ which is only obeyed for atoms in vacuum or free space. Atomic radii may be derived from the distances

Atoms‚ Molecules and Elements Atoms‚ molecules and elements are the building blocks of everything we can see‚ hear‚ and touch. Though not visible to the naked eye‚ it is the combination of millions of these tiny substances that make us who and what we are today. Many elements make up the world around us‚ and each element reacts differently to its surroundings. The definition of reactivity as pertained to chemistry states‚ “The relative capacity of an atom‚ molecule‚ or radical to undergo a chemical

Atoms Atom is the fundamental building block of all stuff‚ or what scientists like to call "matter". An individual atom is very small. In fact‚ the smallest type of atom‚ hydrogen‚ has a diameter of 10-8 cm. Every single object is composed of atoms. Our body is made up of many‚ many individual atoms. There are also many different types of atom. These different types are called elements. Examples of some elements are hydrogen‚ oxygen‚ and helium.
