In this article, we familiarize you with the basic structure of an atom. Basic Diagram of an Atom. Most of an atom is just empty space and consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The center of an atom is the nucleus and one or more electrons surrounding the nucleus.

18 Μαΐ 2021 · When referring to an atom, we simply use the element's name: the term sodium refers to the element as well as an atom of sodium. But it can be unwieldy to use the name of elements all the time. Instead, chemistry defines a symbol for each element. The atomic symbol is a one- or two-letter representation of the name of an element.
The symbols for several common elements and their atoms are listed in Table \(\PageIndex{2}\). Some symbols are derived from the common name of the element; others are abbreviations of the name in another language. Symbols have one or two letters, for example, H for hydrogen and Cl for chlorine.
