Example 1

easy
Describe the basic structure of an atom and identify the three subatomic particles along with their charges.

Solution

  1. 1
    An atom consists of a dense central nucleus surrounded by an electron cloud.
  2. 2
    The nucleus contains protons (charge +1+1) and neutrons (charge 00).
  3. 3
    Electrons (charge −1-1) orbit the nucleus in energy levels.

Answer

Atom=nucleus (protons + neutrons)+electrons\text{Atom} = \text{nucleus (protons + neutrons)} + \text{electrons}
Understanding atomic structure is the foundation of all chemistry. Every atom is electrically neutral because the number of protons equals the number of electrons.
