State the uses of atomic spectra.
(N/A) $1$. Atomic spectra are used to obtain characteristic spectral lines of elements.
$2$. By comparing the observed spectrum with known spectral lines,unknown elements can be identified.
$3$. Thus,atomic spectra (line spectra) are primarily used for the identification of elements.
