rank the group 1a elements tested in order of increasing energy emission when electrons returns to the ground state. explain thi
s pattern in terms of changes in energy levels.
1 answer:
<em>Answer:</em>
- The increasing order of energy emission is as follow
<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>
- These flame color show that when we moved from down the group, the wavelength decreases (frequency increases).
- 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).
