The elementary charge is the smallest unit of electric charge that is considered to be indivisible in classical physics. It is denoted by the symbol \\( e \\) and has a value of approximately \\( 1.602 \\times 10^\{-19\} \\) coulombs. This charge is carried by a single proton, which has a positive charge of \\( +e \\), while an electron, which has a negative charge, carries a charge of \\( -e \\).
