when returning from the excited state to the ground state.
The intensity of the absorbed light is proportional to the
concentration of the element in the flame.
Energy is absorbed or emitted,
when an electron moves from one
state to another. The emission
spectrum consists of groups of
discrete lines corresponding to
electronic transitions.
For Qualitative that determind from the amount of " absorption". It's is based on the same
principle as the flame test used in qualitative analysis. When a calcium, strontium or barium
is heated strongly a characteristic flame colour is brick red. The light that occur from Ion of calcium is gained form the light and up to the higher energy orbital and then the electron falls back into the ground state. Every atom has its own distinct pattern of wavelengths at Which it will absorb energy, due to the unique configuration of electrons in its outer shell.This enables the qualitative analysis of a sample
