  19. 35. <ul><li>The atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electrons . The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except in the case of hydrogen-1 , which is the only stable nuclide with no neutrons). The electrons of an atom are bound to the nucleus by the electromagnetic force . Likewise, a group of atoms can remain bound to each other, forming a molecule . An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive charge ( electron deficiency ) or negative charge (electron excess) and is an ion . An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element , and the number of neutrons determines the isotope of the element. [1 ] </li></ul><ul><li>An atom is a basic unit that makes up all matter . There are many different types of atom each with its own name, mass and size. These are called chemical elements , such as hydrogen or gold . Atoms are very small, the exact size changes depending on the element - they range from 0.1 to 0.5 nanometers . [1] One nanometer is around a hundred times smaller than the width of a human hair . This makes atoms almost impossible to see. The way they work, and how they act with other atoms has to be seen using equations . </li></ul>
