<em>Answer:</em>

  • The increasing order of energy emission is as follow
  •                               Li < Na < K < Rb < Cs

<em>Explanation:</em>

  • The Characteristic colors of alkali metals are
  •                   Li-crimson<em> red</em>
  •                   Na- golden<em> yellow</em>
  •                    K- pale <em>violet</em>
  •                    Rb and Cs- <em>violet</em>
  1. These flame color show that when we moved from down the group, the wavelength decreases (frequency increases).
  2. As the color of Li is red that shows ,it has less emission energy as compare to Rb and Cs that have color violet (more emission energy).
